Summary

Hoary Manzanita is an evergreen shrub native to California and Oregon chaparral, growing as a dense, rounded to spreading shrub about 3–7 ft tall and wide. It features grey-silvery, pubescent leaves that are fuzzy when young and mature to silver, and white to pale pink urn-shaped flowers that bloom in winter to spring.

In cultivation it prefers full sun to partial shade and well-drained, dry soils; drought-tolerant once established and adaptable to a range of soils, including acidic, lean, rocky, and sandy conditions, provided drainage is excellent. Hardiness spans USDA zones 6–10, making it suitable for xeric landscapes and wildlife-friendly plantings, and it attracts bees and hummingbirds.
