About

Ceanothus is a genus of about 50–60 species of nitrogen-fixing shrubs and small trees in the buckthorn family (Rhamnaceae). Common names for members of this genus are buckbrush, California lilac, soap bush, or just ceanothus. The genus is native to North America, ranging from Canada and the United States south through Mexico to Panama, with the center of diversity in the California floristic province of the western United States and Mexico, where around ~42 species are endemic out of the roughly ~58 species in the genus. Most Ceanothus are shrubs, with some species rarely tree-like while others have a short mat-like habit. Species of Ceanothus can be evergreen or deciduous, may have thorns, and also have a diverse number of petal colors ranging from cream to deep blue to pink. Some reproduce strictly from seed, while others can resprout from their roots after a fire.

Where it grows

Plants in this genus are widely distributed and can be found on dry, sunny hillsides from coastal scrub lands to open forest clearings, from near sea level to 9,000 feet (2,700 m) in elevation. These plants are profusely distributed throughout the Rocky Mountains from British Columbia south through Colorado, the Cascades of Oregon and California, and the Coastal Ranges of California.
