It is a shrub native to the Pacific coast and ranges of North America, from British Columbia, Canada to Santa Barbara County, California, U.S.A. It is among the first plants to leaf out and flowers early in the spring. It reaches a height of 1.5–5 m and has lance-shaped leaves 5–12 cm long. Native Americans eat them, make tea of the bark, and chew its twigs to use as a mild anesthetic and aphrodisiac.
