Common names: Portuguese broom; hairy-fruited broom

Cytisus striatus (Portuguese broom) is a perennial shrub (family Fabaceae) found in the San Francisco Bay region, Peninsular Ranges and south coast of California. It is commonly found in coastal scrub and grasslands, where it is expected to continue to expand its range. Portuguese broom was introduced as a landscape ornamental, and is often confused with Scotch broom (Cytisus scoparius). Broom is unpalatable to most livestock except goats, so it decreases rangeland value while increasing fire hazards. These leguminous plants produce copious amounts of seed, and may resprout from the root crown if cut or grazed.
