Rancho Santa Ana Botanic Garden


The California Botanic Garden (formerly the Rancho Santa Ana Botanic Garden) is a botanical garden in Claremont, California, in the United States, just south of the San Gabriel foothills. The garden, at 86 acres (35 ha), is the largest botanic garden in the state dedicated to California native plants. It contains some 70,000 native Californian plants, representing 2,000 native species, hybrids and cultivars. The seed bank has embryos for the thousands of rare plants.

The garden has an active research department, specializing in systematic botany and floristics. The herbarium of Pomona College, housed at the garden, was transferred from the college in 1996. It holds over 1,200,000 specimens. The journal Aliso is published by the organization semiannually. The garden offers graduate degrees in botany through Claremont Graduate University.
