About

Ceanothus verrucosus is a species of shrub in the family Rhamnaceae known by the common names wart-stem ceanothus, barranca brush, coast lilac and white coast ceanothus. It is endemic to northwestern Baja California and San Diego County, where it grows in coastal sage scrub and coastal succulent scrub habitats. It is considered a rare species north of the international border, as most of the valuable coastal land that hosts this plant in the San Diego area has been claimed for development. In California, several extant populations still remain scattered around the region, such as one protected at Torrey Pines.

Where it grows

This species is found in the United States and Mexico, where it is found in coastal San Diego County, California and northwestern Baja California. In the United States, the distribution of this species is threatened by rampant coastal development, fire suppression, and activities along the international border. It is believed that of the extant occurrences in the United States, five have been extirpated and eight have last been seen only 30 years prior. In Baja California, this species is distributed along the Pacific coast from Tijuana to the vicinity of El Rosario. It is also found on Cedros Island.
