Arctostaphylos viscida is a species of manzanita 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 glandular. 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 inflorescences of urn-shaped white to pale pink flowers.
The fruits are shiny red or greenish-brown drupes between one half and one centimeter wide. It is native to California and Oregon. The Miwok of northern California used the fruits to make cider.
Requires a deep moist well-drained light or medium lime-free loam in sun or semi-shade. One report says that this species succeeds in alkaline soils (a rather surprising comment considering the general needs of the genus - it is more likely that the plant can grow on limestone so long as the soil remains acid).Shade tolerant but plants produce less fruit when they are grown in the shade. Prefers a cool damp position. A very ornamental plant, it is sometimes cultivated for its medicinal uses. (info source: pfaf.org)

Prepare your seeds. Manzanita seeds have a hard coating that must be broken down before planting. Soak them in boiling water to loosen the coating.
In nature, manzanita seeds germinate after forest fires, and some gardeners sow the seeds and then burn three to four layers of pine needles on top of the soil to prompt germination.
Cold stratify for 60 days in fridge in vermiculite or sterile soil in airtight container or bag.
Plant the seeds in light well-drained soil 6 mm (1/4") deep.
