Hall's bush lupine

Family: Fabaceae · Type: shrub · Native

Conservation status: CNPS 1B.1

Hall's bush lupine is a rare (CNPS 1B.1) California native shrub found in southern coastal mountain ranges including Santa Barbara, San Bernardino, and Peninsular Ranges in coastal sage scrub and chaparral at elevations below 1,500 meters. Flowering from April to June, this plant produces distinctive purple to blue flowers 14 to 18 millimeters long in compact clusters. Growing 50 to 150 centimeters tall with an upright, rounded form, it features greenish-hairy branches that create a dense, textured appearance. Its compound leaves are composed of 5 to 7 narrow, elongated leaflets that spread outward from a central point, giving the shrub a delicate, feathery texture. Its silvery-green foliage and vibrant flower clusters make it a striking component of southern California's dry mountain landscapes.
