Edgewood Preserve

         (554 plants)

Purple Mouse Ears
Edgewood Natural Preserve is located off 280 in San Mateo County. Its serpentine grasslands are famous for their magnificent displays of wildflowers each spring.

There are lots of good ways to learn the plants at Edgewood. A docent program provides guided plant walks every weekend day during the spring bloom. You can learn online at the Friends of Edgewood Field Guide. Also, "Flowering Plants of Edgewood Natural Preserve" by Toni Corelli describes each plant in detail.

And, of course, you can learn about them here. Thanks to Dennis Smith at NRDB.org and the Friends of Edgewood for this list.
