Agave 'Blue Glow'

Agave 'Blue Glow'
Handsome, small agave, its stiff leaves -- to 1-1.5" wide and blue-green with red margins edged in yellow and a red terminal spine -- are particularly lovely when backlit. Plants are small, only 1-2 ft tall and wide at maturity. This hybrid between A. ocahui and A. attenuata was created by Kelly Griffin. It is solitary, enjoying full sun, good drainage, and little summer water. Frost hardy to at least 15F, mid USDA zone 8, with good drainage, of course, and possibly lower.
Agavaceae/Asparagaceae

Agave 'Burnt Burgundy'

Agave 'Burnt Burgundy'century plant
Probable hybrid of A. victoriae-reginae and A. pelona from Gregg Star who chose it for its unusual, smooth, burgundy-tinted leaves with dark margins. Plants are small, to only 1 ft to 18" tall, and slowly form clumps to expand their presence in full to part sun and lean, well-drained soil. Frost hardy so far to a little under 20F, just below USDA zone 9, in our now Eucalyptus-shaded agave patch, but a fine pot specimen in colder climates. (Eucalyptus mulch optional.)

Agave 'Grey Puppy'
Aptly named for its tendency to generate pups, this cultivar is similar to A. parrasana. To 12-18 inches tall in tight clusters of mostly triangular grey leaves with black-tinged spines. Great for containers or in the rock garden in full sun, dry conditions and well-drained soil. USDA zone 8b at least if kept dry.
Agavaceae/Asparagaceae

Agave 'Kissho Kan'

Agave 'Kissho Kan'lucky crown century plant
Stunning blue-gray leaves edged in white make this symmetrical rosette an outstanding addition to any collection. Yellow leaf spines darken to reddish brown adding distinction. To 15” tall x 18” wide and slowly offsetting. Needs light, and well-drained soil. Frost hardy to 20F, USDA zone 9. Best in container protected from winter wet where temperatures drop into the teens F or sit in the low 20s.
Agavaceae/Asparagaceae

Agave 'Ruth Bancroft'

Agave 'Ruth Bancroft'shark skin agave
Found in the hills near Saltillo, Coahuila, Mexico, where 3 century plants converge (perhaps collide). This selection, from the California garden of Ruth Bancroft, has an exquisitely fine, platinum-colored sheen with no white markings, clearly showing its A. victoria-reginae and A. scabra parentage. To 2-3 ft tall x 3-4 ft wide. For bright sun and well-drained soil with little summer irrigation necessary. Great in containers. Cold hardy to 10F or so, USDA zone 8. Also known as A. ‘Sharkskin’ for its leaf color and texture.

Agave aff. macroculmis T73-99
These, from the mountains of Tamaulipas in Nuevo Leon, Mexico at 7120 ft, are almost undoubtably a stable hybrid between A. montana or possibly A. gentryi - both high mountain dwellers - and A. scabra as it sneaks up toward the passes. Light-blue leaves, deeply dentate, form rosettes to 3ft. Tolerates moderate shade if well drained, otherwise full sun. Frost hardy to 15F, mid USDA zone 8, possibly below 10F if kept dry in winter.

Agave americana 'Cornelius'
Miniature form of the monstrous century plant, forming rosettes to under 2 ft, each leaf centered green with pleasing cream to gold leaf margins. In stunted form gives whole plant the appearance of a star. Frost hardy to upper USDA zone 8 or a bit colder if dry and under an the eaves or another protected spot in winter. Either way a fabulous pot plant. Full sun.
Agavaceae/Asparagaceae

Agave americana 'Mediopicta 'Dwarf Alba''

Agave americana 'Mediopicta 'Dwarf Alba''dwarf white-striped century plant
Beautifully variegated, diminutive form spreading to no more than 2-3 ft, with rosettes of beautifully curved leaves colored a dusty blue-green with a wide creamy stripe in the center. Slowly offsets in bright light and well-drained soil with occasional summer water but lovely as a single plant. As luck would have it, this form is hardier to frost that many, with plants surviving 10 to 15F, USDA zone 8, in soil that is dry in winter. Pull in or cover below 20F or so in areas of winter wet.

Agave americana 'No-Po'

Agavaceae/Asparagaceae

Agave americana 'Opal'

Agave americana 'Opal'opal century plant
A variegated agave from the larger group often just called Marginata’ or ‘Variegata,’ this one most pleasingly variegated in creamy yellow on upright, blue-green foliage with sharp spines. To 4-5 ft tall and wide. Shared with us by plantsman Tony Avent as having been hardy in coastal Virginia. Though it has been nuked in North Carolina below 10F with winter moisture, it does show promise as being one of the tougher of the americana group as a very similar plant has grown unharmed in Portland gardens for a number of years. We expect at least 15F, mid USDA zone 8, and possibly lower if winter dry. In any zone a striking pot or container plant. Sun, well-drained soil, and little summer water.

Agave americana ssp. protoamericana century plant
A robust, stout, particularly silver-blue form from northeastern Mexico, the 6 ft or larger rosettes have proven a bit more moisture and cold resilient than its cousins. Surviving temperatures of 10 to 15F, USDA zone 8, with good drainage, it reaches its greatest potential in large containers or in the open ground. Makes a fine focal point.
Agavaceae/Asparagaceae

Agave bracteosa

Agave bracteosaspider agave
Looking more like a bromeliad, this agave’s lax, spineless leaves are very choice. Polycarpic and rare in cultivation, these plants are found clinging to the high rocky mountains between Saltillo and Monterey in northeastern Mexico growing with pines and, yes, even Douglas fir and they love the cool summer nights of the Northwest. Slow growing, each rosette to 1 ft tall x 18" wide, gradually forming a wider clump. Sun to part shade in well drained soil with occasional summer water. Frost hardy to 10F, USDA zone 8, when kept dry in winter.

Agave filifera ssp. schidigera 'White Stripe'

Agavaceae

Agave funkiana 'Blue Haze'

Agave funkiana 'Blue Haze'
Selected for its striking foliage, the powdery leaves toothed and narrowing to a sharply pointed tip with a pale to nearly white mid-stripe. Rosettes can reach up to 2 ft tall and wide. Sun and well-drained soil required. Drought tolerant but occasional summer water speeds growth and generally enhances the appearance. Frost hardy to 15F, mid USDA zone 8. Otherwise a happy container plant.
Agavaceae/Asparagaceae

Agave funkiana 'Fatal Attraction'

Agave funkiana 'Fatal Attraction'
Another selection of the already handsome A. funkiana, this with darker green leaves and and pale green midstripe down the center. Leaves are narrow and toothed, ending in a dark and pointed spine tip. For sun and well-drained soil, as one might expect. Drought tolerant but occasional summer water speeds growth. Less frost hardy than the species, to 15F, mid USDA zone 8 if kept dry in winter. Does well in containers.
Agavaceae/Asparagaceae

Agave geminiflora

Agave geminifloratwin-flowered agave
A rare relative in the Agave filifera group, this southwestern Mexico native has intriguing deep green rosettes of rubbery, somewhat weeping leaves with enchanting silver-white filifers toward the center of the rosette. Can even produce a short trunk. A tender species damaged under about 20F, USDA zone 9, it is best in a tall pot where its weeping foliage can spread out and over the rim. When the plants reach 1 ft. or more in diameter, they produce a spike of flowers well over 5 ft tall at which time, hopefully, they also produce an offset or two. Frost hardy in USDA zone 9, these are tender and damaged under 20F.
Agavaceae/Asparagaceae

Agave gentryi 'Jaws'

Agave gentryi 'Jaws'hardy century plant
From an intriguing group in an intriguing and floristically rich part of the world, northeastern Mexico's Sierra La Peña, where three agaves inhabit the upper slopes from 8-9,000 ft, this one now accepted as the species A. gentryi. This selection, made by the Yucca Do boys in the early 1990s, has beautiful gray-green rosettes of sharply pointed leaves with deeply indented leaf margins, double, reddish teeth, and embossed impressions of the older leaves on emerging new growth. Has been very slow to offset. To about 24-36" tall, this selection, found amid pines and oaks in light shade on rubbly limestone outcrops, accepts a myriad of garden conditions but resents wet leaves sitting in the crown. So far, unharmed in upper USDA zone 7 winters.

Agave gentryi x montana
Collected originally in the Sierra Madre Orientale of northeast Mexico in an area where the majestic A. gentryi meets the more refined and smaller A. montana. The beautiful silver-gray color represented here suggests that A. scabra, the universal partygoer of that region, has come along for the ride as well. Fast growing to 4 ft wide, this stunning plant is tolerant of garden moisture -provided drainage is good - and prefers full sun for best color. Cold hardy to 10F, USDA zone 8.
Agavaceae/Asparagaceae

Agave gracilipes

Agave gracilipes
The name A. gracilis applies to a group of plants in northwestern Texas into New Mexico, natural hybrids between A. lecheguilla and A. neomexicana. This forms blue-gray rosettes of narrow leaves with horizontal striping. Rosettes of about 12” make a dense colony if allowed. Bright light and average to gritty, well-drained soil. Collected in the Guadeloupe Mountains in southeastern New Mexico at 6200 ft making frost hardiness probable well into USDA zone 6.
Agavaceae/Asparagaceae

Agave havardiana

Agave havardianahavard's century plant
One of the best and hardiest agaves, with olive-green or, often, dusty-blue, curving leaves in the classic agave shape. Big, robust, and wickedly spined, usually as a solitary rosette though sometimes with pups. To 2 ft tall and wide. Best with good drainage and full sun. Frost hardy to -10F, USDA zone 6, or lower. Found in Texas, New Mexico, and Coahuila, Mexico.

Agave kerchovei
For the masochists among us, this most intriguing indeed. Extremely sharp and jagged century plant, a narrow endemic of warm southern Mexico look more like a great white shark's tooth than a plant. The blue-green leaves are edged and spined in white. Growing 2 to 3 feet high and wide in full sun. Alas, only frost hardy into the upper 20s, USDA zone 9.9. Best in container protected from winter wet. Fabulous container plant, nowhere near helium balloons.
Agavaceae/Asparagaceae

Agave lophantha 'Splendida'
A brightly-colored, compact agave native to Mexico and south Texas that reaches no more than 12" tall and 18" wide. Dagger-like leaves are dark green with a light green interior stripe and possess serrated teeth along its margins. This exceptional good-looking cultivar is great in pots and can be planted in mass for great effect. Can be planted in full or sun or light shade. Hardy to 0 degrees.

Agave neomexicana

Agave neomexicanamescal
A tough-as-nails species, closely related to A. parryi but with narrower, deep blue leaves held upright and out and adorned with gray marginal spines and long, terminal brownish red spines. Slow growing to an eventual 1-2 ft tall x 2-3 ft wide, offsetting to form colonies. After 15 years or so, produces yellow flowers on a 12 ft stalk! Full sun and lean, well-drained soil with little, if any, summer water. This native of southeastern New Mexico is one of the hardiest species; tolerating temperatures to -20F, USDA zone 5, with good drainage.
Agavaceae/Asparagaceae

Agave ocahui

Agave ocahuinerf® spined agave
This symmetrical and architectural century plant from Sonora -- to under 18" to 2 ft with shiny forest-green leaves and cream to mahogany edges -- is underutilized in both garden and container. The flowers stems are quite narrow, to 12 ft or more in height after several years, but it is really the unusual rosette we are after. Our favorite specimen is in a deep brown Chinese urn that reflects the color of the leaf margins. Low to medium nutrients maintain compact growth. This collection, by Greg Starr from one of its northern sites a few miles south of the Arizona border, has been frost hardy to nearly 10F with good drainage. Protect in containers below upper USDA zone 8.
Agavaceae/Asparagaceae

Agave ornithobroma

Agave ornithobromamaguey pajarito
Wonderful, short-trunk forming species from subtropical western Mexico, these collections from Sinaloa at under 500 ft elevation -- did we say warm? Closely related to A. geminiflora, the 18" rosettes, with extremely narrow, flexible leaves of dark green, are beautifully framed by a gazillion curly white filifers or hairs. Quite happy with a fair amount of summer moisture; winter drought decreases chance of problems. Full sun to dappled shade, in a bright window, or your nearest lava outcrop. We have had this in our garden, hardy for the last few years with luck. Should be protected below the mid 20s F, so best for mildest parts of the world or as fabulously small-scale container plants. Frost hardy in USDA zone 9.
Agavaceae/Asparagaceae

Agave ovatifolia

Agave ovatifoliawhale's tongue agave
One of the most beautiful century plants, found in the Sierra de Lampazos in the early 80s by the late great plantsman, Lynn Lowrey and only named in 2004 by agave-ist Greg Starr. Growing in a limited range of pinyon/juniper/oak country above 8000 ft, the exceedingly wide, beautifully toothed and chalky blue rosettes can reach over 5 ft in width giving the appearance of a much more tropical species. Has proven to be one of the best performers where cold and wet is experienced in winter and has, thus far, proven hardy to 0F, USDA zone 7, or even a bit lower. Sun to dappled shade; drainage is always a plus.

Agave ovatifolia 'Frosty Blue' whale's tongue agave
A Cistus introduction. This mega-century plant, first discovered by Lynn Lowrey in northeastern Mexico some 30 years ago and just named recently by agaveist Greg Starr, might be the largest of the cold hardy agaves, reaching eventually to 6-8 ft with beautifully formed, blue leaves. Our selection, made from a more recent batch, has a distinct, pale aquamarine hue with the classically shaped leaves, cupped, upright, and slightly outward bending. The species has taken the cold and wet of Dallas TX, for instance, so upper USDA zone 7 for cold hardiness; possibly colder in gritty or dry soil. Fabo container plant.
Agavaceae/Asparagaceae

Agave parryi var. huachucensis

Agave parryi var. huachucensis
From, yes, the Huachuca Mountains in southern Arizona and into northern Sonora, this beautiful gray-blue century plant forms a classic 20-24” artichoke shape, eventually offsetting to form small colonies. From mid-elevation (5-7000 ft) this, though not the most frost hardy of the parryi clan, takes 10 to 15F in stride, mid to upper USDA zone 8, lower if very well drained. Full sun and summer water in Mediterranean areas.

Agave parryi var. huachucensis 'Huachuca Blue'
A Cistus introduction, bluer than its near relation. Our fabulous selection -- from 7000 ft in the Huachuca Mountains in southern Arizona and into northern Sonora -- exhibits particularly steel-blue leaves in the classic 20-24” artichoke shape, eventually offsetting and forming small colonies. Full sun in lean, well-drained soil with occasional summer water in dry climates. Though not the most frost hardy of the A. parryi clan, still takes 10F in stride, USDA zone 8, and lower if very soil is well drained.
Agavaceae/Asparagaceae

Agave parviflora ssp. flexiflora

Agave parviflora ssp. flexiflora
Another rare plant from southeastern Arizona and further south with small jewel-like rosettes of under 6" consisting deep olive-green leaves marked white with occasional filifers and eventually producing narrow spikes of red-tinged flowers. Occasionally offsetting -- rather than off-putting. For sun and well-drained soil. Accepts average moisture if the soil is well-drained. Frost hardy at 12 to 15F, mid USDA zone 8.

Akebia longiracemosa 'Victors Secret'

Akebia longiracemosa 'Victors Secret'chocolate vine
Most unusual for the genus with attractive evergreen leaves, almost butterfly-like, and racemes, to 5" or more, of vibrant purple-pink flowers lasting a long season. Otherwise the same fascinating (intimidating?) fruit aging to a nearly metallic blue. All this on a vine of about 10 ft; not as vigorous as some others. Full sun for best flowering though perfectly at home in shade. Frost hardy in USDA zone 7, to just above 0F.

Alnus formosana [Tayuling 2004] formosana alder
Native to Taiwan at mid to high elevations, this was of interest to us for its evergreen habit, the glossy green leaves holding fast, we expect, in temperatures down to 18 to 20F. Though loving damp conditions, these do not require quite the riparian situation of many alders. Fast growing, to 30-40 ft tall, in sun to part shade with summer water. Stand back! Ultimate cold hardiness is not yet tested but these will remain healthy, though deciduous, to the bottom of USDA zone 8.

Alocasia x 'Portora'
The Arnold Schwarzenegger of Alocasias, A. 'Portora' is a muscular beast , growing 6-8' or more in a single season as a juvenile and 10-12' as an adult. Magnificent leaves are heavily scalloped with thick, ropy veins. Plant in mostly shade. You will likely believe this plant has died during winter before it reincarnates itself in spring much like Arnold did in the first Terminator film. Likes frequent watering during summer, but too much water during winter, especially when young, is a no-no. Plant in rich, well-drained site with thick layer of winter mulch. Hardy to 10-15 degrees.
Araceae

empty

Aloe 'Blue Elf'
A very attractive clumping, upright, blue-leaved aloe that sends up purple-brown stalks of bright orange flowers in late winter to early spring. In general, a tight and compact plant, to 2' x 2'. Due to its somewhat upright habit, it looks best in a small, low pot or planted in the ground in a sunny location. It will do fine in shade, but will lose its blue color and will not flower much, if at all. Hummingbirds would flock to each of their orange flower spikes, if only they were around in February. Water infrequently. Zone 9.

Aloe 'Brass Hat'

Aloe 'Brass Hat'
A most wonderful Hummel hybrid with dark bronzy leaves and rosettes forming clumps of 6” to 1 ft adorned throughout the year with brassy orange flowers. The cross, as follows -- A. (A. haworthioides x A. bakeri) x ((A. descoingsii x A. calcairophylla) x A. bakeri) -- seems algebraic and daunting. The plants are not. Alas, frost hardy only to about 25F, mid USDA zone 9, so take precautions. Great container plant. Keep dry in winter.

Aloe 'Marmalade'
A new aloe hybrid with green leaves that age to blue and is textured with orange marmalade-like semaphores. Prized by collectors for its technicolor dreamcoat appearance and bumpy, moon-like surface. If it were a dragon, it would possess magic beyond this world and engulf evil with flames of pure gold. Plant in containers and water infrequently. Zone 9b.

empty

Aloe 'Moondance'
A new aloe hybrid that is virtually pure white with tiny dot-matrix-like markings all along its leaves. Slow-growing, but clumping and pupping easily. This is a handsome aloe to pair with others in a pot, especially with more typically green and blue-green hybrids. Move indoors in winter unless you live in zone 9b or above. Orange-red flowers open atop slender stalks in warm conditions. Prefers very good light, but no direct sun.

empty

Aloe 'Quicksilver'
Enormously pleasing small aloe with very light green, almost white, serrated leaves and dark green spotting. Several spikes of orange-red blooms emerge from the center in late spring and possibly again in fall, if you're nice. Excellent in containers or as a kitchen window specimen. Part sun with occasional watering.Not frost tolerant.

empty

Aloe 'Sunset'
This dramatic upright hybrid to 18" or more sports blue-green leaves, toothed and edged in red as well as coral red flowers. Stalks will branch from the base. Best in warm conditions, i.e. Zone 10, or in containers. Bright light, let dry in winter and between waterings.

Aloe aristata torch plant
Haworthia-like creature from high elevations of South Africa forming rosettes to 5-6” with each leaf spiked and mottled with cream zigzag markings. Slowly offsets, clumping to form wonderful architectural patterns. Dappled to full sun, decent drainage, and summer water where dry. Probably the most cold hardy, non grass-like Aloe, accepting at least 10F, USDA zone 8, and below into upper zone 7 when planted in the ground. Possibly even lower if kept dry in winter.

Arctostaphylos densiflora 'Harmony' harmony manzanita
Another special manzanita. Taller and larger-leaved than other cultivars of the species, this one simply has more of that California manzanita, “summer water is for pansies” presence to it. The dark, mahogany bark is enough for me, and lovely with the pink bell flowers in spring. Evergreen, to 6 ft tall or so x 5 ft wide in well-drained soil; full sun on the coast and, perhaps, a bit of afternoon shade inland. Drought tolerant but accepts occasional summer water. Cold hardy to 5F, mid USDA zone 7.

Arctostaphylos manzanita 'St. Helena'
From Napa Valley in California, a beautiful form of a very useful genus in the west -- plants to 6 ft or so in time, or to 10ft if helped along a bit. Deep green leaves of only about 1” and dark mahogany stems. The late winter flowers are white aging to shell pink. Very happy with summer drought, but also, unlike many manzanitas, willing to tolerate some summer garden water -- but only some so best not to overdue it. Mineral soil is best and full sun to dappled shade. Sadly, intolerant of conditions in the east coast states.like North Carolina and Idaho. Low USDA zone 8.

From Northern Lake County California "amid a grove" of like-minded manzanitas, this form is particularly large -- to 15 ft or more but easily maintained at 4-5 ft -- with an upright habit, red stems, and green leaves slightly tinted mauve. Outstanding as a backdrop with very pale pink flowers occurring anywhere from the end of December through February. And yes, there is more ... most attractive, muscular, orange-red bark to set it all off. Of all our recent selections, this is among the top. Full sun to lightly dappled shade with good air circulation. More tolerant than most of some summer garden water but don't overdo it. Frost hardy in USDA zone 7.

Aristea major blue sceptre
Of this intriguing group of blue-flowered irids mostly from South Africa, we had thought this species too tender for permanent planting in these parts, but they have thriven for many years now, giving us courage. Easy in average garden conditions and luscious with summer water, with bright green, iris-like leaves to 2 ft or a bit more, and clusters of sky-blue flowers from spring through fall -- all from the small inflorescence, so don't cut them back. Bright light is best. Outstanding planted with yellow foliage nearby. Evergreen to the upper teens F, upper USDA zone 8; regrowing, especially with mulch, from 10F or so. (Also known as Aristea capitata.)

Aspidistra caespitosa 'Jade Ribbons' cast iron plant
Shared with us years ago by Barry Yinger, this small, cast iron plant produces leaves, to only about 18" in height, in dense clusters of deep green with a satiny blue finish. Intriguingly beautiful for gardens or containers in medium shade to the deepest, darkest recesses of the garden. Fairly fast growing in the southeast due to hot summer nights; on the West Coast, they are slower but worthwhile. Regular summer water in dryer climates to push them along a bit, though they can go without for long periods. Undamaged at 10 to 12F, USDA zone 8, if out of wind; can recover from 0F, zone 7.

Aspidistra elatior 'Amanogawa'

Aspidistra elatior 'Amanogawa'cast iron plant
First introduced to the US, we believe, by Barry Yinger, this diminutive evergreen perennial, to about 1 ft or so in height, has very shiny leaves in dense clumps, each leaf stripped and splashed various shades of gold. Not the most stable creature in the world ... but then, neither are most of our friends ... and should be relieved of the occasional rogue green sport that might appear. Slow growing but one of the more striking variegated cast iron plants. Fine in even the very darkest shade with summer water to establish and for faster growth. Excellent container plant for medium to very low light. Frost hardy to -20F, USDA zone 6.

Astelia chathamica 'Silver Spear' silver spear
The largest of a beautiful group of agave/hypoxiodes (phormioides?) ... whatever ... with dazzlingly silver rosettes, this one making an offsetting clump from 3-5 ft high and wide with 3-4" wide leaves. The stunning silver effect is best, for us, in light shade. We keep our specimens in single rosettes as they are most striking, giving away the offsets (or selling them at extraordinarily high prices...But for you...) Love well-drained soil, though certainly don't mind being continually moist. Not fond of prolonged drought. Avoid excessive summer heat. One of the best and most striking container specimens. This species, frost hardy to the upper teens F, upper USDA zone 8, recovering from 10 to 12F. If those temperatures are expected, at least go out and throw a tarp over it. It's ok, all of us have been seen in our bathrobes doing the same thing.

Astelia nervosa 'Westland'
A relatively recent escapee from New Zealand...(no, we don't mean it has invasive potential; New Zealanders are generally very courteous) and doubtless a hybrid between A. nervosa and A. fragrans. Very pretty, clumping rosettes, roughly 18" tall spreading to 2 ft with downy covered leaves, adding hues of gold and silver tending toward maroon with winter's coolness. Slightly slower growing for us than A. n. 'Red Gem', but a very nice complement. You need them both. Full sun for best color as well. Winter color at its best in cooler climates. Regular water. Great container plant. Undamaged to at least the low teens F, mid USDA zone 8, possibly colder.

Our favorite A. nivicola collection, New Zealand natives, forming clumps to 2 ft wide by roughly 18" tall with numerous leaves all coated with a soft silver fur and turning deep red, almost burgundy, with light and frost in winter. Very striking! This has been one of the toughest creatures, having not had frost damage even in our 14F, arctic extravaganza in 1996. Also an amazing container plant where burgundy tones in rosette-forming plants are hard to come by. Prefers even summer moisture in bright light for best color, though accepting of shade. Tolerant of frost to 10F, USDA zone 8, with reports of near 0F out of the wind.

Banksia integrifolia

Banksia integrifolia
Loveliest large shrub to small tree from southeastern Australia. This handsome protea, to about 15 ft or even more, has beautifully serrate leaves when young, later on becoming nearly entire with reflective, silver-white undersides. Once plants reach 3-4 years of age, "corncob" flowers appear, to 4-5" tall, held upright as candles. To us they smell of baking bread or...corn. To their pollinators, I suppose baking bread would smell very much like a banksia. Reliable in upper USDA zone 8; freezes back to its lignotuber at 15F. Where temperatures fall below, keep in a pot to bring inside. Bright light to dappled shade in sandy soil. As with all proteas, watch the phosphorus. We fertilize ours with alfalfa pellets.
Proteaceae

Banksia marginata

Banksia marginatasilver banksia
Evergreen shrub to small tree with a dense canopy of long, narrow, finely toothed leaves, medium green on top and silvery underneath for a bright, bicolor appearance.

Beschorneria aff. yuccoides ssp. dekosteriana - large green
These seedlings from plants originally collected from Mexico’s Tamaulipas State have grown larger than any others we have tried. The succulent, deep green rosettes reach to over 4 ft wide and high and occasional cherry-red and green flower spikes, to upwards of 10 ft, suggest giant hummingbirds hovering just out of sight. Possibly the best attribute of this wonderful plant -- and the whole genus for that matter -- is its agave-like texture coupled with a willingness to grow in medium shade though perfectly at home in full sun in all but the lowest, hottest places. Occasional summer thunder storms, or the equivalent thereof, simulate its mountain forest home. Frost hardy in upper USDA zone 7, having lost its leaves but recovered from around 10F in gardens…not ours, thankfully. (Originally sold as Beschorneria aff. decosteriana - large green; the name now conforming to accepted taxonomy.)

Carpenteria californica - Sean’s Clone
Though it's name is not the most imaginative, this plant is from our collection, around 1990, in its limited distribution in the foothills of the Western Sierra Nevada. It is a particularly vigorous clone with a rounded form, large, glossy leaves that remain a bit more sturdily evergreen with summer drought, and nice clusters of late spring flowers, white with yellow stamens -- smaller than the popular cultivar 'Elizabeth,' but more numerous and with ruffled petals that appear almost double. Can be trimmed into a hedge or "lifted" to reveal the flaky, golden bark. Accepting of summer water on the West Coast, these are also quite drought hardy in well-drained soil and full sun to dappled shade. Frost hardy to 8F, upper USDA zone 7.

Ceanothus griseus 'Atomizer'atomizer carmel creeper
A Cistus introduction. This sport of the variable 'Diamond Heights' occurred in our garden, the leaves splashed with microdots of gold and green - no not a virus but really attractive. Given that, we dubbed the plant atomizer as the foliage indeed looks painted lightly with spray paint in various shades of green cream and gold. Only slightly less vigorous than the species. A superb container and/or garden plant preferring, for us, a bit of afternoon shade. Native of protected coastal climes, these should be protected below 15-20F. Tolerant of some summer garden water.

Chaenomeles sinensis false quince
This false quince from China suggests an artists rendition of what a quince could be in its ultimate expression. A large, graceful shrub to small tree, to about 12 ft, the bark exfoliates beautifully in jigsaw puzzle patterns of bronze, orange, and cream. The foliage is rounded to about 4", and a pretty, shiny green, turning coppery orange and red in late fall, and often remaining through the winter only to shed as new growth appears or with severe cold. Careful pruning maintains small tree shape. Early spring flowers of apple blossom pink give way to rounded, yellow, waxy fruit, sort of papaya-shaped to about 6", with a strong fragrance of quince and lemon. Wonderful for an indoor bowl of "living potpourri", refreshing an entire room ... possibly the whole neighborhood. A plant for bright light to only dappled shade. Drought tolerant though summer water speeds growth. We know it is frost hardy in USDA zone 7; probably ok, but deciduous in zone 6.

Cordyline australis cabbage palm
Much overused as an annual though much better as a perennial resident where temperatures allow. Eventually grows into a small tree with multiple crowns of palm-like, bright green foliage just before freezing to the ground in a bad winter, then starting over again. Quite permanent along the Oregon coast or wherever temperatures stay above 20F, USDA zone 9.

Cordyline australis - Wanaka Lake, NZ
At first we thought this collection was C. pumilo but these are slowly forming trunks, so we expect whatever this is to become a multiple trunked, large shrub, especially thrilling for us in that this was a high elevation collection in a place that regularly visits the teens F in the winter with snow. Leaves are green with a most attractive purple flush for much of the season. Grow as for other cordylines in sun to part shade in dampish soil as a container or garden specimen. Ultimate hardiness as yet untested but we are guessing 15F, mid USDA zone 8.

Corokia x virgata 'Orangerie'
A Cistus introduction. Though we would like to say this lovely plant is a result of years of careful hybridization under tightly controlled circumstances, we actually found it growing on the floor of one of the greenhouses as a tiny seedling. This grows as other C. x virgata forms, to a 6-8 ft shrub, but with a more upright form and butter-yellow-aging-copper-orange leaves with reflective, nearly white, undersides.

Corylopsis spicata 'Aurea'

Corylopsis spicata 'Aurea'golden winterhazel
One of the loveliest winterhazels we have come across, to under 10 ft tall with butterscotch-yellow leaves, tinted orange where they meet sun, and pale yellow flowers in mid winter -- all managed with the same grace we have come to expect from the species.

Cotinus coggygria 'Golden Spirit' golden smoke bush
Making the rounds for a couple of years now, this mid-sized smoke bush, growing to about 8 ft, has the richest golden-yellow leaves, that, rather than toasting in our hot summers, burnish an ever-so-slight orange...we like that! Dense foliage produces airy pink flowers that suggest the common name of smoke bush and brilliant fall foliage colors of pink, orange, and yellow. Growing 8+ ft x 8 + ft and flowering in May-July, the shrubs like full sun to part shade, lean, well-drained soil, and some summer water - though quite drought tolerant once established. Can sulk in heavy wet clay or too much fertility. Easily stooled to create an exuberant perennial. Frost hardy in USDA zone 5.

We use this as a pull-in plant in both containers, either mixed and alone, treating this much as we would an Aeonium with cool, damp, but bright conditions in the winter, letting dry when temperatures become hot.

Dudleya lanceolata

Dudleya lanceolatalanceleaf live-forever
Known as lanceleaf liveforever, this collection from Tim Hannis, taken in the California's San Bernadino Mountains at over 3500 ft, has succulent, narrow and pointed, blue-green leaves and appears in colonies of powder-blue starfish in gravelly spots and outcrops. In summer, clusters of yellow to red flowers appear on stalks to 2 ft tall. Adaptable to various soils but requires good drainage. Accepts droughty conditions as well as abundant water and sun to part shade. So far has been frost hardy to close to 0F, USDA zone 7, with superb drainage and dry summers.

Dyckia 'Naked Lady'

Dyckia 'Naked Lady'
Named for the lack of spines along the leaves, this cross between D. encholirioides x D. brevifolia is a terrestrial bromeliad with sharp-tipped, shiny green, strap-like leaves arranged in rosettes to 1 ft tall and 2 ft wide. Forms colonies rather quickly. In spring, bright orange flowers appear on tall stems. Part sun to bright shade is best with moderate water. Frost hardy to 20F, USDA zone 9. Happy in containers where temperatures drop lower.
Bromeliaceae

empty

Dyckia 'Nickel Silver'
Rosettes of long, narrow, silver-gray leaves with hooked white spines set this dyckia apart. Summer flowers are orange on red stems to up to 4 ft tall. Individual plants are 6-10" tall x 15" wide, eventually forming larger clumps. Expects well-drained soil in sun to part shade with little summer water once established. Frost hardy to 16F, upper USDA zone 8. Fine in containers that are protected in winter.
Bromeliaceae

Dyckia 'Red Devil'

Dyckia 'Red Devil'red-leafed dyckia
This, one of the most colorful Dyckia in our collection and a probable hybrid between D. platyphylla and D. leptostachya, grows to 10-15" high and 18" or so wide in reasonable time with elegantly spined rosettes of deep olive green, burnished intense red, more so with more light. Spring and summer flowers are of burnt orange atop 2 ft stalks. One surprise is the reported frost hardiness, with some testimonials to 8F though we'd be a bit skittish there; we're more confident in the mid teens briefly, mid USDA zone 8, probably colder if dry. Fine container plant, a bit slow growing and offsetting so will remain within bounds for some time.
Bromeliaceae

Dyckia choristaminea

Dyckia choristaminea
Terrestrial bromeliad with succulent, spidery leaves mottled deep purple and forming rosettes to only about 4.” Flowers are produced in summertime clusters of orangey red.

Ficus aff. heterophylla DJHS 4307
This, one of several forms revolving around or closely related to this lovely fig, was shared with us by plantsman Dan Hinkley, its having been successful for several years in his garden near Seattle,WA. To 6 ft or more and deciduous with red-tinted stems and long, narrow leaves, lobed toward the end and also tinted an orange-red in sun. We have found it to be an endearing texture in our garden. Has been frost hardy to 12F in Washington so we are rating this as at least low USDA zone 8 though relatives have sailed through mid zone 7, often resprouting vigorously from the base. We here at Cistus have a “thing” for the genus ficus so we are very happy with this one. Seems to tolerate quite a bit of drought but we push our along a bit with extra summer water and at least half sun for best stem and leaf color.

Ficus afghanistanica 'Silver Lyre'

Ficus afghanistanica 'Silver Lyre'
A Cistus introduction...yet another hardy fig. We wonder where it's been all our lives. Native from Northern India to western Iran and Afghanistan and a delicacy there with its small, dark, very sweet fruit. We have selected this form from seed for its entrancing, filigreed, silver-green leaves of about 5-7". So far, ours have been for external use only as we have not tasted the fruit. Eventually might reach 15-20 ft in height; can easily be kept smaller with pruning. Sun to part shade. Very drought tolerant once established. Frost hardy to the upper edge of USDA zone 7 so far.

Ficus heterophylla - small leaf form climbing stream fig
One of several ficus collections by Dan Hinkley and another of our favorites with small, narrow leaves flushed orange, red, and green on a shrub to about 6 ft tall. As with the larger leaf form, creates a most unusual garden texture in full sun to about half shade. Evergreen when temperatures remain above 20F, in USDA zone 9, but may lose leaves in the teens F, recovering nicely in the spring. Looks to be ultimately frost hardy to about 10F, the bottom of USDA zone 8, and probably lower with mulch.

Ficus sarmentosa var. nipponica

Ficus sarmentosa var. nipponica
This cousin of the more common F. pumila, slightly tougher and a bit slower growing, has leathery pointed leaves of about 2-3” and the climbing, clinging, grasping, scraping, prying habits that we all desire… We have ours climbing the trunk of a trachycarpus palm, making a lovely green column. Shade or sun and occasional summer water for more vigorous growth. The best news: it has survived 0F, USDA zone 7, with little damage, though we still suggest mulching, at least where possible, when the next arctic express arrives.

Fuchsia magellanica 'David Palmer'

Fuchsia magellanica 'David Palmer'
Shared with us by Portland plantsman, David Palmer, and named for the same. This southern Chilean collection of a hummingbird's wildest fantasy with 1-2" deep cerise sepals and black-red falls has several unusual characteristics for a species long grow in in Britain and in the western US. It's high elevation provenance has allowed it to remain evergreen or nearly so through our coldest, once-in-several-decades winter, growing into a 12 ft most attractive miniature tree. Our plant is now about 10 ft with the prettiest of golden flaking bark, actually rivaling the beauty of the flowers. A least partially deciduous in the low 20sF.

Leptospermum namadgiensis alpine tea tree
One of the nicest tea trees to come to us in a long time, this shared with us by Paul Bonine of Xera Plants and named after Namadgi National Park on the Australian Capital Territory/ New South Wales border. Only found in the late 80s growing on thin soils at high elevations and introduced to us recently. To 3-4 ft tall with small, shiny, evergreen leaves and spring flowers, white ever so slightly tinted pink, for sun to dappled shade. To us the most striking feature is the bark, peeling in sheets to a light orange. Plants in the garden should be lifted to expose this lovely feature. Good hedging or container plant and rather drought tolerant in the ground. Has been tested so far in this country to as low as 5F with no damage, therefore a confidant USDA zone 7b.

Leptospermum scoparium 'Washington Park Hardy'
Leptospermum scoparium is among the most beautiful of the teas so we were happy to find this one surviving robustly after a 10F winter in Seattle's Washington Park. Though a shrub to under 4 ft at the time there, in our garden, with a little more heat, it quickly lept to a 4 x 8 ft specimen with deep green, burgundy tinted leaves and clouds of white flowers in spring. We kind of think of it as a purple Italian cypress for bright conditions and some summer water especially in dry climates. We declare it hardy easily to the mid teens F so, USDA zone 8b, and possible to mid USDA zone 7.

A member of the michelia group which includes some of the most floriferous of the evergreen magnolias, M. maudiae shows off an abundance of large, white, lemon-scented flowers in early spring, and from an early age -- a perfect contrast to the large, blue-green leaves that remain handsome all year long. Fast-growing, reaching 15-20 ft tall x a somewhat narrow 8-10 ft wide in 10 or so years. A stunning and rewarding tree for sun to part shade with regular summer water. Frost hardy in upper USDA zone 7.

Magnolia stellata 'Royal Star' royal star magnolia
Star magnolias are a frequent sight in early spring with their showy and fragrant white flowers; 'Royal Star' is a popular cultivar with even larger and showier flowers and a slightly later bloom time that helps avoid frost damage to early blooms. A small deciduous tree, slow growing to 10-15 ft x 8-10 ft, these are best in rich, well-drained soil, with regular summer water and dislike extreme conditions, e.g., too dry or too wet. Perfect for a specimen tree or an informal hedge. Frost hardy in USDA zone 4.

Mimulus aurantiacus 'Jeff's Tangerine'
Of all the West Coast natives, the shrubby monkey flowers have some of the most to offer. Evergreen, to about 4 ft or more in the wild, with flowers ranging from butter yellow to oranges to even deep pink. Mimulus a. 'Jeff's Tangerine' came as a seedling in our friend Jeff Rooney's garden. The flowers are a pleasing, yes, tangerine color, with an orange throat and a little creamy yellow around the margins. In years of light frost it has flowered year round, though in the winter cold spell of 2004, temperatures in the low 20s F knocked the flowers off but did little to thwart its luxurious growth. Able to withstand summer drought, it will happily go dormant until fall rains begin. Also tolerant of reasonable garden water if soil is well drained and light is bright, flowering year-round in mid USDA zone 8 or above. Otherwise a fine pot specimen or seasonal addition to containers.

To 4" high x 18" wide, with small, round, 2-3" wide pads that have very short spines and are fragile (pads break off easily). The petite, deep pinkish red flowers in June are abundant. Beautiful in the rock garden or in containers. Fergusen thinks this MAY be Opuntia polyacantha v. schweriniana … still a mystery." Frost hardy to -30, USDA Zone 4.

Opuntia 'Sunset'

Cactaceae

Opuntia aurea 'Coombes Winter Glow'

Opuntia aurea 'Coombes Winter Glow'creeping beavertail cactus
Old opuntia selection that is very hardy but, for unknown reasons, now much harder to find. We like it for the unassuming green pads that turn dark red-purple to nearly black in cold weather. To 2 ft tall and up to 3 ft wide with cerise flowers appearing in June. Tough and easy in lean, well-drained soil with lots of sun and little summer water. Frost hardy to -30F, USDA zone 4.

Opuntia aurea 'Golden Carpet'

Opuntia aurea 'Golden Carpet'
A spineless form of the creeping beavertail shared with us by Kelly Grummons, with upright blue-gray pads with tiny glochids forming chains across sandy areas in its native habitat, making it particularly attractive in both rock gardens and containers. Bright yellow flowers are one of the earliest to appear and one of the last to finish of all species. A variety that always draws a great deal of attention. Often reblooms in July. To 6" high x 36" wide. Frost hardy in USDA Zone 5.
Cactaceae

Opuntia basilaris 'Peachy'

Opuntia basilaris 'Peachy'beavertail cactus
This beavertail cactus, a native from the Mohave desert of California into northern Sonora, was given to us from an old Albuquerque garden and has been one of the best performers. Attractive clumps, from 3-4 ft wide and 18” in height, with 6” pads of powdery blue-tinted-pink, burgundy in winter, and, indeed, peachy pink flowers in spring and early summer. Though a clone more tolerant of garden water, they still prefer well-drained, gritty soil, especially where winters are wet …and an occasional thunderstorm, artificial or not, in dry summer climates. Frost hardy to -30F, USDA zone 4.
Cactaceae

Opuntia basilaris 'Sara's Compact'

Opuntia basilaris 'Sara's Compact'beavertail cactus
One of many fabulous beavertail cactus selections, this is a lovely semi-dwarf form, reaching an eventual 18” with soft, pinkish-gray pads covered in colorful orange-red glochids -- not to be licked! -- and deep rose flowers. This cultivar was selected by Sara McComb. Plant in full sun in mineral soil where drainage is sharp. Frost hardy to -20F, USDA zone 5.
Cactaceae

Opuntia basilaris var. brachyclada 'Mormon Rock'

Opuntia basilaris var. brachyclada 'Mormon Rock'
A Cistus introduction from the vicinity of Mormon Rock in southern California. This tightly clumping small form of beavertail has conical blue pads somewhat more flattened than the typical subspecies indicating a possible hybrid. Whatever the botanical case, each pad is only about 3" wide with well-spaced, bright orange glochids giving the whole plant a very cheery appearance. Nice medium-to-cherry-pink flowers appears in mid spring. Not minding extra winter moisture, these are a bit easier to grow than other beavertails, enjoying full sun. Excellent pot or rock garden plant and frost hardy to -10F, USDA zone 5, probably zone 4.

Opuntia basilaris var. heilii - Type local beavertail cactus
Named for botanist Ken Heil and collected from the northeastern population of the beavertail cactus. This clone, found growing in heavy alkaline soil in south central Utah and collected via a single pad years ago by plantsman Tim Hannis, produces dense clusters of blue-bodied plants, rather short on glochids, a good thing! It has been our favorite so far growing robustly and producing abundant, warm pink flowers in late spring. Easy in in the ground or container provided full sun and good drainage. Frost hardy to at least -30F, USDA zone 4.

Opuntia basilaris var. ramosa beavertail cactus
This far western Mohavian form of one of our favorite beavertails was found many years ago -- possibly an intermediate between the typical brachyclada form. Unfortunately collectors wiped out the colony seemingly within seconds of its discovery. Though we weren't among the collectors, propagules did get around, so here it is -- a pretty thing with each pad under 3", each one stepped atop another and each clump to about 18" tall. Good in containers or in the dry garden. Frost hardy in USDA zone 5.

Cactaceae

Opuntia polyacantha 'Imnaha Blue'

Opuntia polyacantha 'Imnaha Blue'
A Cistus introduction. A common native of western dry lands, this clone, from northeastern Oregon's Imnaha Canyon, was found weeping several feet off a cliff of red ryolite, the nearly spineless, gray-blue pads appearing almost as if hanging in chains. Assuming not everyone has a cliff, these will form spreading mats to 4-12" tall and up to several feet wide. Early summer flowers are a warm, soft yellow. Ordinary cactus requirements -- sun, lean and well-drained soil, and little or no summer water. Undoubtedly frost hardy into USDA zone 4.

Opuntia whipplei 'Tiny Tim'
A Cistus introduction, but we must thank Tim Hannis for finding this northernmost Utah population of O. whipplei and particularly for this striking clone. These spiny, miniature chollas, reaching only about 6-8" in height but spreading to 6 ft or more, are variable in color with 1-2" long "pads" covered with golden spines. Even these small plants manage to produce a number of yellow-green flowers each spring followed by yellow fruit. A most attractive garden "shrub" or container specimen for sun and decently drained soil. Frost hardy to -30F, USDA zone 4.
Cactaceae

Opuntia wrightii - white spine

Opuntia wrightii - white spine
Small cholla from northern Arizona and adjacent places --perhaps more familiar by its old name and synonym, Opuntia wrightii - white spine, this collection does have white spines rather than the silvery spines of the genus. Tightly held branches form a miniature “tree” to about 3 ft tall. Greeny yellow flowers are abundant in mid spring. Easy to grow in bright light and gritty soil with occasional summer water. Frost hardy to -30F, USDA zone 4. A very good container specimen.

Opuntia x rutila - red/black spines

Opuntia x rutila - red/black spines
This so far unnamed hybrid was an early Colorado Plateau collection by plantsman Claude Barr. Stout orange-red and black spines mark pads roughly 3" long, the elongation suggesting parentage by O. polycantha and O. fragilis. Mid spring, yellow flowers fade to apricot. Wonderful for small rock gardens with the usual cactus conditions -- sun, lean and well-drained soil, and little or no summer water. Frost hardy to -30F, USDA zone 4.
Cactaceae

Opuntia x rutilia

Opuntia x rutilia
These seem to be intermediate population between O. polyacantha and the ubiquitous O. fragiis coming from the western Colorado plateau.

Oxalis articulata f. crassipes - good pink form
Old fashioned garden plant from South America, ours selected from among old garden plants in our inherited garden. Both winter and summer growing, the dense tufts of spring-green, shiny, 1/2" leaves are supported by pine-cone-like caudices or tubers. In case Oxalis scares you, this plant rarely seeds and is increased somewhat slowly only by division of the clumps. The cheery pink flowers begin for us in late winter and with good summer water continue -- well... into late winter. This year round flowering can be interrupted only by severe summer drought or winter temperatures below the upper teens F, with which they will go happily dormant only to spring back when their immediate climate changes. USDA zone 7.

Pelargonium 'Persian Queen'
One of the best and brightest of the fancy leaved Pelargoniums, this grows into the typical pot geranium that Gramma loved but with a punk twist -- screaming yellow leaves and cerise flowers. Ours lived through most winters, but, in areas below USDA zone 9, cuttings should be taken annually and dried or rooted in sand for the next year. Plants may also be lifted and stored in a cool place -- with those forgotten potatoes. Excellent container addition, if just for the shock value alone.

Pileostegia viburnoides

Pileostegia viburnoidesclimbing hydrangea
Self-clinging evergreen vine with terminal white flowers in large clusters in late summer to early autumn. Foliage is handsome, the leaves dark green and leathery. For half sun to full shade in fertile, well-drained soil. An excellent candidate to run up that Douglas fir out back, as long as it gets a bit of summer water.

Pinus contorta var. contorta

Pinus contorta var. contortabolander's beach pine
Endemic to a narrow coastal area of California near Mendocino, these pines are often shrubby in their natural, windy habitats, but in less extreme garden conditions they can reach 15-20 ft tall and wide. A two-needle pine with short, narrow needles in this variety and knobby, open cones, these trees are endangered in their natural habitat. Preferring full sun and good drainage, they are adapted to summer water. Frost hardy in USDA zone 8 and best with protection from winter winds.

Pinus eldarica Afghan pin
This dark-needled pine, from Russia and Afghanistan, loves dry conditions, growing quickly when young, eventually reaching 30-80 ft tall by 15-25 ft wide with a symmetrical form, rounding on top over time. Needles are 6" long in sets of two and occasionally 3. Tolerates poor soils but good drainage is best for long term health. Drought tolerant once established, but accepts occasional deep watering, in full sun inland or on the coast where plants tolerate windy conditions. Frost hardy to -10, USDA zone 6.

Pittosporum divaricatum
This plant, on our lust list for years, is in many ways a typical New Zealand citizen, with tiny, only 1/4", narrow, toothed leaves of nearly jet black, providing difficult grazing for beaky animals….all this on a densely upright, divaricating shrub. Eventually to 8 ft or more, but easily kept at 3-4 ft, producing small, blackish purple flowers and, with age, larger leaves. Is there a theme? Striking pot or garden specimen. We suggest planting with silver foliage plants so youngsters don’t get lost or stepped on. Prefers some summer water where dry. Has proven hardy to 10F or so, USDA zone 8.
Pittosporaceae

Pittosporum eugenioides var. minor 'Variegata'

Pittosporum eugenioides var. minor 'Variegata'variegated lemonwood
A smaller version of an attractive species, to only 10 ft or so rather than the 30 ft of its near relation. Evergreen with dense foliage of pale green with white, slightly wavy margins and, in spring, intensely fragrant, spring flowers. Useful as a specimen or hedge. Site out of harsh winds and in a protected spot with full sun and regular summer water. Frost hardy to 10F, USDA zone 8.

Pittosporum heterophyllum

Pittosporum heterophyllumchinese mock orange
This evergreen "mock orange" should be in every shopping center parking lot– it’s that tough. Sadly, it’s not well represented anywhere. Medium shrub to small tree,12 to 15 ft, with glossy, narrow foliage and, in spring, pale yellow, intoxicatingly scented flowers. Delicious! Sun to part shade with regular water. Frost hardy in upper USDA zone 7.

Pittosporum heterophyllum 'Winter Frost'

Pittosporum heterophyllum 'Winter Frost'variegated chinese mock orange
One of the most frost hardy of the Chinese mock oranges, this form, introduced only a few years ago from Japan, grows to 4 ft or so with 2” leaves margined and streaked most attractively in white and cream. Creamy flowers are scented of orange blossoms in mid spring to early summer. Can be shorn as hedge or used as specimen plants in decently drained soil.

Pittosporum illiciodes - narrow leaf cl. 2
Another Cistus selection of a narrow leaf Pittosporum illicioides, the original form selected by Dan Hinkley - P. illicioides DJHT 99079, chosen for the extremely narrow leaves that present a fine texture in the garden. This handsome evergreen shrub, to 12-15 ft tall, has shorter an slightly narrower leaves than P. illicioides 'Strappy' but the same fragrant, white flowers in spring and, in autumn, very small, blue-black fruit in orange capsules. Best in light shade with regular summer water. Frost hardy in USDA zone 8 and expected in zone 7.
Pittosporaceae

Pittosporum illiciodes 'Cloud Nine'
A Cistus introduction. From our ongoing selections, this particularly fine-textured mock orange possesses all the qualities of 'Strappy' but with finer texture and somewhat denser growth habit. To an eventual six feet in height, a unique feature is the profusion of orange scented flowers emerging in clouds prior to the onset of new growth in spring, thus making them particularly visible. The fragrance wafts for some distance. These characteristics, combined with the fact that we've made lots of cuttings, means you need one as soon as possible! Dappled to full sun, medium drainage and drought-tolerant though, monthly deep watering once established is helpful for extra new growth in dry places. USDA Zone 7.
Pittosporaceae

Pittosporum patulum

Pittosporum patulum
A most unusual member of the genus from New Zealand southern South Island, endemic to only a couple of spots along the Bellcloutha River. Growth is narrow and upright to 8-15' with black, spidery leaves in youth enlarging only somewhat in adultitude with more rounded bright green leaves and a multitude of deep maroon flowers said to be the most fragrant of the genus, reminiscent of carnations. This should make a fine new addition to the garden, especially the Goth garden. We have surmised hardiness to zone 8 that has been verified by surviving 12F in winter 2014 in the garden of our super friend Loree, where she and the plant survived the winter unscathed.
Pittosporaceae

Pittosporum tenuifolium 'Argentea Nana'

Pittosporum tenuifolium 'Argentea Nana'
Of the often jewel-like members of this highly selected species from New Zealand, P.t. 'Argentea Nana' is indeed one of the most exquisite. Young plants form mounds, 18" to 2 ft , of densely held, 1/4" leaves on black stems. As plants emerge into their adult phase, the leaves grow farther apart and the plants become more open. This too is attractive but if one misses the old days, a little shearing can never hurt. On older plants late spring flowers are under 1/3", maroon to nearly black with the fragrance of dianthus. Dappled shade to full sun with regular summer water preferred. Exquisite container plant. Frost hardy in USDA zone 8.
Pittosporaceae

Pittosporum tenuifolium 'Atropurpureum'

Pittosporum tenuifolium 'Atropurpureum'purple kohuhu
Though doubtless many purple-leaved forms have been introduced under the name Pittosporum tenuifolium 'Atropurpureum', this one is ours, grown from cuttings of the lovely 12 ft tall x 4 ft wide specimen in the garden of Western Hills Nursery in Northern California. The 1", rounded leaves, yes purple and held among black stems, and carnation-scented, nearly black flowers, might possibly sound morbid but are, in fact, dazzlingly beautiful. Plants, easily kept as a formal element or background hedge in the garden, are easily shorn to maintain even tighter shape. Prefers bright light or only dappled shade with regular summer water in dry climates. This has proven to be one of the frost hardiest cultivars, surviving 7F briefly in the garden at Western Hills in 1990 and having turned not a leaf with a windy 20F in our garden. Frost hardy to at least 10F, USDA zone 8; a container plant or an experiment in zone 7.

Pittosporum tenuifolium 'Gold Star' Kohuhu
Yet another selection, this a compact, evergreen shrub with bright, cheerful foliage, olive green centrally splashed golden, on black stems, and intensely fragrant, tiny black flowers in spring. o 4 ft tall or so and as wide. Full sun in milder climates to part shade in hot, dry areas. Likes well-drained soil and some summer water. Frost hardy in USDA zone 8a.
Pittosporaceae

Pittosporum tenuifolium 'James Stirling'

Pittosporum tenuifolium 'James Stirling'silver kohuhu
One of the parents of the ever-popular Pittosporum tenuifolium ‘Silver Sheen’, 'James Stirling' is also appealing with a much more platinum coloration and a denser habit. Tiny black flowers in spring come and go quickly but are a sweet surprise and lovely against the silvery foliage. Happy in full to part sun with regular summer water, James will get to 10 ft tall or so and half as wide. Can be pruned to increase density and maintain shape. One of the hardier forms, accepting temperatures in the single digits, upper USDA zone 7.
Pittosporaceae

Pittosporum tenuifolium 'Nutty Leprechaun'

Pittosporum tenuifolium 'Nutty Leprechaun'dwarf purple kohuhu
This selection originated in Ireland though its parentage is, of course, from New Zealand. A good addition to the purple-leaved pittosporums, growing only to about 3 ft tall with small, deep burgundy leaves, under 1/2”, a striking contrast with the florescent chartreuse of the new spring growth. These are not only compact, they have an almost creeping quality, separating P. t. ‘Nutty Leprechaun’ from other small, purple cultivars. Also one of the tougher of the purple group, these have been frost hardy so far into the low teens F with no noticeable damage. Full sun for best color. At home on the West Coast of North America, but not happy in the hot, humid southeast. Frost hardy in lower USDA zone 8.
Pittosporaceae

Pittosporum tenuifolium 'Purpureum'

Pittosporum tenuifolium 'Purpureum'purple kohuhu
"Odd" is one way to describe this fabulous and much sought after pittosporum with wavy-edged leaves that start out pale green and mature to a deep bronze-purple, the new growth against the dark, older leaves giving a striking bicolor effect. Wow! In winter the shiny and reflective foliage appears even darker. A nice, evergreen shrub, to 10 ft tall. Best in full to part sun with average summer water. Cold hardy in USDA zone 8.
Pittosporaceae

Pittosporum tenuifolium 'Silver Ruffles'

Pittosporum tenuifolium 'Silver Ruffles'ruffled kohuhu
Small, gray-green, wavy leaves float above black stems on this delicately textured shrub, possibly reaching 12 ft in time. Tiny black flowers appear in spring, stunning against the foliage and highly fragrant as well. Best when backed by darker foliage. Site out of wind and close to a path to be admired. Sun to part sun in hottest climes with some summer water. Frost hardy to at least 10F, USDA zone 8.

Pittosporaceae

Pittosporum tenuifolium 'Victoria'

Pittosporum tenuifolium 'Victoria'victoria kohuhu
Another new Pittosporum for us and, we believe, for the United States as a whole, this one having the reputation of one of the most frost hardy in New Zealand. Compact plants with upright dense form, to 6-8 ft, with 1/4", nearly round leaves, splashed pink and silver -- reminiscent of P. tenuifolium ''Silver Magic' but to our eyes darker in color and more compact. Same culture as for others: well-drained soil, bright light, and even summer moisture. Frost hardy to 10F, USDA zone 8; possibly 7 with protection.

Plagianthus regius lowland Ribbonwood, manatu
Lovely small, deciduous tree from New Zealand, to 20 ft tall x 6-7 ft wide, that begins as a dense shrub with interlaced branches and matures to a graceful, upright, adult form with lateral branches and wavy, nearly black stems holding toothed leaves. Pale yellow-green flowers appear in late spring in large panicles. Tolerant of poor soils and dry conditions but enjoys consistent summer moisture. Dislikes intense summer heat with humidity. Perfect for the sunny coast or in dappled shade inland. Surprisingly, specimens from Cistus took single digits in several places in the winter of 2009 so we expect hardiness to frost in USDA zone 8.

Pleioblastus shibuyanus 'Tsuboi'
Who knew such a tongue twister could be so beautiful? This small and unusual, spreading bamboo has bright, variegated foliage, green with cream stripes, on arching canes that lounge lazily on other plants. Arching clumps reach 4-6 ft tall easily and possibly 9 ft as a cheerful, single specimen or a bright, dense hedge in part to full sun. Frost hardy to -5F, USDA zone 6b.

Podocarpus alpinus 'County Park Fire'

Podocarpus alpinus 'County Park Fire'alpine plum yew
OoooH! We think we are becoming quite enamored with these little podocarps. Another down-under plant selected by famed County Park Nursery in the United Kingdom, this jewel-like little conifer, reaches only about 3 ft with densely held, shiny, rounded needles of deepest green/maroon in summer, taking on fiery purple-orange tints in winter, especially in new growth. A fabulous addition to container or garden. The P. alpinus group is one of the most hardy of the genus, this plant having been hardy to close to 0F in several gardens. Stunning when planted with other party goers such as Uncinia rubra and, maybe our favorite, Libertia peregrinans for a rusty contrast. Average soil conditions; bright light best; not appreciative of prolonged drought. Frost hardy to 0F, USDA zone 7.

Podocarpus chinensis - Yucca Do

Podocarpus chinensis - Yucca Do
Though the name is somewhat questionable, the plant is certainly not. Given to us by Yucca Do Nursery some years ago, this Podocarp spends several years as a delightful conical shrub with narrow, spring green foliage of about 1” in length; we are told it can eventually grow into a large tree of 30’ or more. So far this gem has withstood temperatures into the upper single digits Fahrenheit with no visible damage. We find it, however, thirsty for some summer water in our part of the world.

Podocarpus chingianus UCSC 95-97
Related to P. chinensis, these rare podocarps grow to an eventual 20 ft tall, a striking architectural feature for the garden, with "needles" of 1/2" held against the stem giving an almost tufted appearance. Best in full sun or the light understory. Though drought tolerant, growth can be boosted by light summer watering. Frost hardy to 10F or so, USDA zone 8, and possibly lower.
Podocarpaceae

Podocarpus falcatus UCSC95.340

Podocarpus falcatus UCSC95.340sickle-leaved yellowwood
A graceful podocarp reaching large tree size in the highlands of the eastern South African Drakensberg range and a medium grower -- to 30 ft or so at least so far -- in our Western gardens. As the South African podocarps have never been thought to be the most frost hardy creatures in the world, we were surprised to find this successful (until removed by chain saw) at the JC Raulston Arboretum in USDA zone 7 in North Carolina. The thin stemmed, upright tree, with somewhat weeping branches and almost bamboo-like, narrow curving foliage, provides grace for specimen or background planting in the garden. Though somewhat tolerant of drought, prefers regular irrigation to keep from becoming spindly. Full sun to medium shade, average fertility and drainage. Frost hardy in USDA zone 8, possibly 7 if in North Carolina.

Podocarpus macrophyllus - self-fruiting clone Kusamaki
Shared with us some years ago by plant geek buddy, Mike Remmick, originally from his stay at the North Carolina State University Arboretum, now the JC Raulston Arboretum in Raleigh, NC. Though he has not been able to locate the original plant during our many trips to this fabulous institution, Mike's specimen has grown to a beautifully conical, 12 feet ... ok...minus one bout of falling into a creek...but it's back. This form is particularly desirable to us, not only because of its hardiness, having survived well below 0F in Raleigh, but also because of its heavily powder-blue dusted foliage and quite attractive red "berries" produced with no playmates in sight. Average garden conditions; dappled shade to bright light with decent drainage and summer water. Doesn't turn down a little manure once in a while. Frost hardy to at least USDA zone 7.

Podocarpus salignus

Podocarpus salignuswillowleaf podocarp
One of a number of exquisite and rare conifers from southern Chile, this upright, forest dweller with weeping branches and gracefully hanging foliage looks for all the world like the bamboo you always wanted. Particularly beguiling as it grows in several places with the Chilean native Chusquea culeou, a combination we observed during our first collections in Chile some years ago. Nothofagus and luma are other associates in this moist cool maritime environment. Unlike some other rarities, it has become quite at home in cultivation, adding a graceful subtropical effect in our courtyard and having remained undamaged in temperatures in the low teens F in several gardens. A plant for reasonably moist soil and average fertility, bright light to dappled shade (weeps a bit more in dappled shade). Eventually to 25-30 ft, more reasonably to 15 ft in the garden.

Poncirus trifoliata x Citrus sinensis ‘Rusk’ sweet orange
A hardy, evergreen citrus, also known as a Citrange or sweet orange, with the trifoliate leaves of its Poncirus parent, but a bit larger and darker. White, sweetly scented flowers in spring. The orange fruits are small with a reddish flush, and though somewhat less bitter than their Citrange relatives, still, are best used for juice -- or simply as garden adornments. Plant in fertile, moist, well-drained soil in a sunny position. Plants are tall, to 6-8 ft, vigorous, and frost hardy to USDA zone 7, though, as new growth is susceptible to frost, they benefit from a protected site. Very nice in container with proper watering, just as soil becomes nearly dry. A citrange, one of the oldest, developed in 1897 and named for J.M.Rusk, the first Secretary of Agriculture. Who knew? Vigorous, small, evergreen to semi-evergreen tree, with Poncirus’ trifoliate leaves and thorns. Fruit is orange flushed with red, seedless, and less bitter than a Poncirus, useful in juice, maramalades, etc. Sun with regular summer water. Frost hardy to 0F, USDA zone 7.

Pseudopanax discolor - Nelson, NZ
Fascinating evergreen aralia from New Zealand, this particular purple-leaved form from serpentine soils in Nelson, South Island, NZ. Shrub to small tree -- to 15' to 20' but easily kept as small as 3' by nipping -- produces palmate leaflets, somewhat fan-shaped, and the deepest green, tinted purple in summer, darkening to a rich purple in cooler periods. Small, sputnik flowers, typical of the Aralia family appear in spring and summer followed by dark berries that add to the plants attractiveness in fall. A plant for moist woodland conditions or a bright garden in parts of the country where summers are not unreasonably warm. Consistent moisture; a little organic matter is a plus but fairly low fertility overall is preferred. Wonderful container plant. Frost hardy in the upper reaches of USDA zone 8; totally reliable in zone 9.

Our collection from northwest Argentina at nearly 10,000 ft. Gracefully arching, very shiny leaves tinted red are stunning growing from a high cliff. Luckily you do not have to hang by your ankles to have this plant. Has flowered for us with rosey red, 2 ft spikes with a celadon blue flower, a color that should not be found in nature. Should be hardy to at least 10 to 15F, mid USDA zone 8, making it one of the toughest bromeliads for garden use. Full sun to dappled shade; good drainage.

Quercus aff. rugosa - La Siberica strain
This is from our 1991 collection from high valley in Mexico's Nuevo Leon state and named for the town and the cold climate from which it comes. In habitat these form dense 6-8 ft shrubs with undulate and glossy fiddle-shaped leaves, deep green and ever so lightly furry above with a thick woolly coating of cream to light orange fur beneath. OoooH! Our original seed collections have grown in our somewhat more lavish conditions to 15 ft small trees just large enough tshow off the reflective undersides of the leaves. OoooH! OooH! From its habitat we suggest this might well be frost hardy into USDA zone 6 but we know zone 7 is a no-brainer. Ohhhhh, ohhh, ohhh!

Quercus glauca japanese blue oak
Previously Cyclobalonopsis glauca. Beautiful oak, or oak relative depending on one's taxonomic belief, from southeast China to Japan and Taiwan. This blue-tinted creature can reach 60-80 ft but seems content at 20 ft in our part of the world. It had a brief stint of popularity in Portland in the 50s, then as far as we can tell, became almost completely unavailable. The silvered bark and blue undersides of the leaves make this one of the prettiest, medium-sized garden trees available for warmer climates. Not fussy but likes supplemental summer water in dry climates. Good for sun or shade. Frost hardy in upper USDA zone 7. (The beautiful specimen at the JC Raultson Arboretum in North Carolina was damaged severely but recovered quickly at around -8º F.)

Quercus hypoleucoides

Quercus hypoleucoidessilver oak
We first fell in love with this plant in the 1980s upon seeing a collection from an expedition of Boyd Kline and Frank Callahan to northeastern Mexico. Our first up close and personal experience was on New Year's Day, seeing these exquisite 25 ft tall by 15 ft wide trees in the Chiricahua Mountains of southeast Arizona where, under bright blue skies and with a few inches of snow on the ground, the dazzling sliver undersides of the leaves reflected as if illuminated by spot light. Fast growing when young. The narrow leaves are very leathery and shiny and can age to maroon on the upper surface in cold temperatures. A plant for sun, well-drained soil, and quite possibly hardy into low to mid USDA zone 6. But we are sure about zone 7. Our favorite oak, really.

Ribes 'Pink Pearl'pink currant
A Cistus introduction. Though this new cross should involve long story about an involved, Cistus hybridization program, in fact, this was a seedling in our garden ... for which we are happy to take credit. And yes, it's possible the world doesn't need another Ribes sanguineum cultivar, but this one's different ... with dense, hanging clusters of late winter flowers that open white and fade to a warm pink. Flowers very well and we believe represents a color combination not in the trade. Typical western native plant care is required in lean soil and dappled shade -- though for this one full sun can't hurt --. with summer water to be applied sparingly and carefully only in cool weather. We expect frost hardiness to at least the bottom of USDA zone 7.
