Renowned for its spring wildflower displays and rare serpentine habitat, Edgewood is a prime example of California’s extraordinary floral diversity. Our state has more plant species than any other, one-third of which are endemics, growing nowhere else in the world. Edgewood Preserve is a precious microcosm of this increasingly-threatened natural diversity.

In less than one square mile, the preserve supports over 570 plant species, including thirteen rare and endangered plants, across 9 plant communities: woodlands (Oak Woodlands, Mixed Evergreen Forest), grasslands (Serpentine Grassland, Annual Grassland), shrublands (Serpentine Chaparral, Chamise Chaparral, Northern Coastal Scrub), wetlands (Freshwater Wetland, Seasonal Riparian).

You’ll find our complete flora on the Edgewood Plant List.
