Zoom To My AddressZoom To California Estimated Plant Range

About Eastwood Manzanita (Arctostaphylos glandulosa) Eastwood's manzanita is a shrub native to the coastal slopes of western North America from Oregon to Baja California. It can be seen in southern California among granite peaks. This is an erect shrub reaching up to 2.5 meters in height. It is bristly and sometimes hairy, secreting sticky oils. Eastwood manzanita has edible fruit and white flowers that attract birds. It is quite variable in appearance and there are several subspecies scattered across its range, some of which are rare. It grows from a basal burl from which it can resprout after a fire.

It seems to do best if planted in the spring, when it can grow quickly and establish itself before the dry summer months. It handles weekly water for the first year after planting, after which it's best to naturalize. Plant on slopes or well draining flats. It will look green and vibrant year round if it can stretch its roots out to a nearby damper spot or irrigated area. It likes sun or part shade.

Propagation ?
For propagating by seed: Soak in concentrated H 2 S04 for 4-15 hrs. (USDA Forest Service 1974). For the acid treatment, single nutlets and stone pieces (often without embryos) and entire stones should be treated separately, as they require different amounts of time in acid (Giersback 1937) For all species an alternate method is fire treatment in fall, this gives germination by spring. More easily propogated from tip cuttings in winter using bottom heat.
