Presidio Manzanita (Arctostaphylos hookeri ssp. ravenii) is a rare native shrub whose only documented location in the wild is in Presidio Park, San Francisco. It is listed by State and federal agencies as an Endangered Species. The U.S. Fish and Wildlife Service says that only one individual of this subspecies remains in the wild and no wild seedlings of this plant have been observed. However, it has been propagated from seeds and cuttings for conservation purposes, and it is sometimes available for garden use. It was formerly classified as Arctostaphylos hookeri ssp. revenii and some sources may still refer to it by that name.

Presidio Park, San Francisco
Chaparral, Northern Coastal Prairie, Northern Coastal Scrub
This plant can be used with most other northern chaparral plants. However, due to its rarity in the wild, it would be shown to best advantage when used with other plants commonly found in the vicinity of Presidio Park, such as Yerba Buena (Clinopodium douglasii), Oneleaf Onion (Allium unifolium), Sitka Columbine (Aquilegia formosa), California Mugwort (Artemisia douglasiana), Hairy Ceanothus (Ceanothus oliganthus), Blueblossom (Ceanothus thyrsiflorus), Canyon Dudleya (Dudleya cymosa), Mission Bells (Fritillaria affinis), Broadleaf Stonecrop (Sedum spathulifolium)
