Devoted to California native plants — and all the wildlife and people who love them — the Garden advances knowledge, conservation, and appreciation of California native plants.

California Botanic Garden (formerly Rancho Santa Ana Botanic Garden) is the largest botanic garden dedicated exclusively to California native plants. Spanning 86 acres in Claremont, it features over 22,000 California native plants across roughly 1,170 taxa, including rare and endangered species. It is accredited by the American Alliance of Museums and operates as a 501(c)(3) nonprofit offering public gardens, conservation research, and education programs.
