Regional Parks Botanic Garden

The Regional Parks Botanic Garden is a botanical garden within Tilden Regional Park spanning approximately 10 acres of land organized into sections representing different geographical regions of California. Each section displays plant species that naturally grow in those particular landscapes.

The garden was established in 1940 and developed into a center for preserving and studying California's diverse native plant species. Its founding reflected a growing interest in protecting and understanding the state's local flora.

The garden demonstrates how different parts of California support their own plant communities and how this diversity draws people interested in learning about the local flora they might encounter elsewhere. Visitors notice how the layout of each section mirrors the natural landscapes those plants come from.

The garden is accessible daily at no cost, with guided tours available on weekends to deepen your understanding of the plants. Wear comfortable walking shoes since the grounds are hilly and there is much to explore on foot.

The site holds one of the most comprehensive collections of California conifers and oak trees in one place. Additionally it preserves about 300 rare and endangered plant species that appear in state inventories.
