Wildflowers of the San Francisco Bay Area

"People exploring nature in the greater San Francisco Bay Area can use this handy photographic field guide to identify annual and perennial (non-shrubby) native wildflower species. The flowers in the guide are grouped by color to make identification as easy as possible, and the accompanying text indicates size, bloom period, and other characteristics of each plant. The guide’s six double-sided panels fold up into a packet narrow enough to fit in a back pocket yet sturdy enough to stand up under repeated use. Lamination has also made the guide waterproof. The plants identified in Wildflowers of the Bay Area grow in a large region that includes the valleys,  mountains, and coastal plains of 10 counties including San Francisco, San Mateo, Santa Cruz, Santa Clara, Alameda, Contra Costa, Solano, Napa, Sonoma and Marin."
