| Arctostaphylos hookeri var. ravenii | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
Raven's manzanita is a low-growing evergreen shrub with urn-shaped white to pink flowers. It was rediscovered by Peter Raven when he was a young boy in San Francisco in 1952 (it was described as subspecies ravenii in 1968). There is one naturally occurring plant left in its native habitat, located on a slope facing the Pacific Ocean in the San Francisco Presidio. This area is now managed by the Presidio Trust, a government corporation.
