Hairy Manzanita
Arctostaphylos columbiana

About Hairy Manzanita (Arctostaphylos columbiana) Arctostaphylos columbiana is a species of manzanita known by the common name hairy manzanita. It is native to the coast of western North America from northern California to British Columbia. This large manzanita is a treelike shrub occasionally reaching heights of up to ten meters. It is erect with hairy branches, the smaller twigs bearing long bristles tipped with sticky glands. The leaves are oval-shaped and may be 6 centimeters long and 3 wide, dull green, fuzzy, and hairy on both surfaces. The small, white, urn-shaped flowers are borne in bunched flower clusters. The fruit is a red drupe about a centimeter in diameter. The seed requires either fire or consumption by animals in order for germination to occur. This manzanita grows in forested areas and has been known to become a weed on Christmas tree farms.
