Cistus Nursery

*RETAIL - Quercus tomentella [Arroyo Grande]

*RETAIL - Quercus tomentella [Arroyo Grande]

Quite rare in commerce, this striking tree, to 30 ft tall or so and endemic to the islands just off the coast of southern California, has 4" adult leaves that look very much like Lithocarpus densiflorus -- rather glossy green, rounded ovals with most attractive pleats particularly visible on the silvery undersides. Prefers sun and dry summers but tolerates average garden conditions as long as the drainage is good. These make good street trees or specimens for the mid-sized garden. Frost hardy to the upper end of USDA zone 7.

Planting Recommendations

Under most conditions, planting directly into the garden is best. Keep in mind, that in our care, plants have been protected from intense sunlight and drying winds and would therefore require sheltered transition time in order to acclimate to such conditions in your garden.

All plants going into containers (rather than in the ground) should be potted immediately in well-drained potting mix and watered well to ensure the soil is fully moistened with no air pockets. Succulent plants abide by different rules (**see below).

Plants held for later planting are best stored in a cool greenhouse or a well-lit garage or basement, rather than in your house where conditions are likely too warm and dry.

Those plants needing time to acclimate can be set out in pots and provided some shade and shelter for the first week to allow for a successful transition.

**For cacti and other succulents, we recommend using a soil mix of less than 30% organic matter, preferably a 2-1 blend of cactus/succulent potting soil and pumice, perlite or lava rock. These plants are sensitive to prolonged heavy moisture, especially in cool/winter conditions. Keep this in mind when watering them for the first time. It is better to leave them dry in lower temperatures.
