Data Coverage 3 of 6 dimensions
Hairy manzanita is a native evergreen shrub found on open, rocky coastal slopes from British Columbia to central California. Its distinctive hairy twigs and persistent foliage make it identifiable year-round. It dominates exposed ridgelines and coastal bluffs where few competitors thrive.
Grows 3 to 10 feet tall in full sun to part shade with low water needs and well-drained soil (Zones 7a to 8b). Slow growth and moderate lifespan suit it to rocky, infertile sites. Provide minimal supplemental water once established. Watch for black root rot, leaf gall, and Phytophthora dieback in wet settings; manzanita leafgall aphids may cause cosmetic galls.
