About Hooker's Manzanita (Arctostaphylos hookeri) Arctostaphylos hookeri is a species of manzanita known by the common name Hooker's manzanita. This shrub is endemic to California where its native range extends from the coastal San Francisco Bay Area to the Central Coast. This is a low shrub which is variable in appearance and has several subspecies. These are generally mat-forming plants or low bushes with small green leaves, dense flower clusters of white to pink flowers, and shiny egg-shaped or round red drupes. It does not form a burl and can be killed by fire.

Hooker's Manzanita comes in a number of subspecies and cultivars. Two low growing, mounding forms include ssp. hearstiorum and Monterey Carpet (about 1 foot tall and 6 feet wide). Upright forms can reach 6 feet in height. In general, this species prefers full sun within a few miles of the coast, and part shade when more inland. This plant will tolerate some summer water (1-2x per month). It prefers dry, well drained, acidic soil and is slow growing. It is a great candidate for a rock garden or coastal bluff garden.
