About Franciscan Manzanita (Arctostaphylos franciscana) Franciscan Manzanita (Arctostaphylos franciscana) is a rare native shrub. It is presumed to be native only to the immediate vicinity of San Francisco Bay and was presumed extinct for many years. It is on CNPS list 1B.1. However, it has been in cultivation for many years and is considered a good garden Manzanita for both coastal and inland locations. It tolerates a wide range of conditions. It was formerly considered to be a subspecies of A. hookeri and some sources still refer to it that way.
