Edgewood Botanic Garden is a small botanical garden in Mill Valley, California, on the southeastern side of Mount Tamalpais. Covering less than one acre on Edgewood Avenue near Cypress Avenue, it is devoted to native plants of the region. The garden reflects the landscape of the California coast ranges, where Coast redwoods dominate, and includes about ten other tree species, some native to the area and others from similar habitats elsewhere in the California Coast Ranges. It is not currently actively maintained.
