About RSABG

Who are we? RSABG is the largest botanic garden dedicated exclusively to California's native plants. Founded in 1927, the Garden is nestled into 86 acres in the city of Claremont, near the foothills of the San Gabriel mountains.

The Botanic Garden is a private, non-profit organization, open 8:00 a.m. to 5:00 p.m. Groups of 10 or more are encouraged to make reservations in advance by calling, at 909-625-8767, ext. 206.

Our Mission Statement: Rancho Santa Ana Botanic Garden promotes botany, conservation, and horticulture to inspire, inform, and educate the public and the scientific community about California’s native flora. The Garden is devoted to the collection, cultivation, study, and display of native California plants and to graduate training and research in plant systematics and evolution. Through all its programs, the Garden makes significant contributions to the appreciation, enjoyment, understanding, and thoughtful utilization of our natural heritage.
