Ceanothus verrucosus is a species of shrub in the buckthorn family Rhamnaceae known by the common names wart-stem ceanothus, barranca brush, and white coast ceanothus. It is native to Baja California and San Diego County, where it grows in coastal chaparral and scrub. Most of the valuable coastal land that hosts this plant in the San Diego area has been claimed for development, but several populations still remain scattered around the region, such as one protected at Torrey Pines.
