Wild Plants of the

East Bay Regional

Park District

A Photographic Guide Sorted by Family Name

Photographs by Wilde Legard Botanist, East Bay Regional Park District

Revision: February 23, 2007

More than 2,000 species of native and naturalized plants grow wild in the San Francisco Bay Area. Most are very difficult to identify without the help of good illustrations. This is designed to be a simple, color photo guide to help you identify some of these plants.

The selection of plants displayed in this guide is by no means complete. The intent is to expand the quality and quantity of photos over time. The revision date is shown on the cover and on the header of each photo page. A comprehensive plant list for this area (including the many species not found in this publication) can be downloaded at the East Bay Regional Park District’s wild plant download page at: http://www.ebparks.org.

This guide is published electronically in Adobe Acrobat® format to accommodate these planned updates. You have permission to freely download, distribute, and print this pdf for individual use. You are not allowed to sell the electronic or printed versions.

In this version of the guide, the included plants are sorted alphabetically by scientific family name, and by scientific name within each family. Under each photograph are four lines of information, based on upon the current standard wild plant reference for Cali-fornia: The Jepson Manual: Higher Plants of California, 1993.

Scientific Name Scientific names revised since 1993 are NOT included in this edition.

Common Name These non-standard names are based on Jepson and other local references.

Origin & Longevity Native or Introduced. Annual, Biennial, Perennial, or a combination.

Scientific Family Name The scientific plant family name according to Jepson.

A separate guide sorted by scientific name is also available. For readers that prefer a guide focusing on showy wildflowers, sorted by flower color and emphasizing common names, please download the “wildflower” version of this guide.
