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.

Spread across 86 acres in Claremont, California, the Garden is located approximately 35 miles east of Los Angeles. Nestled in the foothills of the San Gabriel Mountains, the Garden offers beautiful mountain vistas. The Garden displays about 2,000 taxa of the approximately 6,000 native plant taxa in California and includes those native to the California Floristic Province as a whole. This region extends into southern Oregon, far-western Nevada and extensively into Baja California, Mexico.
