The California Seed Bank at CalBG is the largest seed bank dedicated to the long-term conservation of California’s native flora.
The Seed Conservation Program at California Botanic Garden is responsible for the management of the California Seed Bank and the Garden’s seed collecting endeavors. The seed bank comprises over 5,700 accessions representing more than 2,300 California native plant species and cultivars. The geographic scope of the CalBG collection encompases the entire state of California as well as the Mexican portion of the California Floristic Province. Particular emphasis is placed on the rare plants of Southern California. These collections help protect our most threatened plants from extinction, conserve material for habitat restoration, and serve as source material for research as well as for living collections at botanic gardens for increased public education and appreciation.
