About Whiteleaf Manzanita (Arctostaphylos viscida) Arctostaphylos viscida is a species in the Ericaceae (Heath) family known by the common names whiteleaf manzanita and sticky manzanita. This is a treelike shrub reaching up to five meters in height. The stems may be smooth or fuzzy, and are often hairy. The leaves are rounded to oval, sometimes slightly toothed or with hairs along the edges, and usually dull green on both surfaces. When in flower the shrub is packed heavily with densely bunching flower clusters of urn-shaped white to pale pink flowers. The fruits are shiny red or greenish-brown drupes between one half and one centimeter wide. Seeds require fire for germination. This is a plant of chaparral and coniferous forests of 3,000-5,000 ft. elevation. It is native to California and Oregon. The Miwok of northern California used the fruits to make cider.
