The garden contains over 2,000 species and varieties of native California plants, many of which are rare or endangered in the wild.
It is one of the few botanical gardens in the world that focuses strictly on the flora of a single political region.
The garden includes a reconstructed 'fossil' forest display reflecting prehistoric vegetation patterns in California.
Volunteers and staff utilize seed-collection trips throughout the state to ensure the garden's genetic diversity remains high.
The garden layout purposefully mimics the north-to-south geographical arrangement of California's plant communities.
The Regional Parks Botanic Garden is a 10-acre living museum dedicated exclusively to the native flora of California. Located within Tilden Regional Park, the garden is organized geographically to represent the state's diverse ecological regions, including the Sierra Nevada, the coast, and the desert. It serves as an essential repository for rare and endangered California native plants, focusing on botanical conservation. The site features a redwood grove, a dry creek bed, and specialized displays for plants from the Channel Islands and the Klamath Mountains. Visitors can walk through meticulously labeled zones that demonstrate how different California ecosystems function. The garden functions as a public resource for botanical education and sustainable gardening practices. It is maintained by the East Bay Regional Park District.
