About the Rancho Santa Ana Botanic Garden

Rancho Santa Ana Botanic Garden was founded to promote botanical knowledge, conservation, and landscape use of California's native plants.

As a private, non-profit, research and educational institution, with extensive library, herbarium, and laboratory facilities, the Garden is responsible for the Botany Program of the Claremont Graduate University. Active research in systematic and evolutionary botany, as well as the Garden's horticulture and community education programs, focus on native California plants and their conservation.

The garden is located on the same property as the Grow Native Nursery, which sells California native plants.

The mission of the Garden is to make significant contributions to the appreciation, enjoyment, conservation, understanding, thoughtful utilization and stewardship of our natural heritage.
