A photographic guide to
showy wildflowers of
Anthony Chabot
Regional Park
Sorted by
Flower Color
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 showy wildflowers 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 and 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, only showy wildflowers are included. These wildflowers are sorted first by flower color, then by plant
family (similar flower types), and finally by scientific name within each family. Under each photograph are four lines of information,
based on the current standard wild plant reference for California: The Jepson Manual: Higher Plants of California, 1993.
Common Name
These non-standard names are based on Jepson and other local references.
Scientific Name
Scientific names revised since 1993 are NOT included in this edition.
Origin & Longevity
Native or Introduced. Annual, Biennial, Perennial, or a combination.
Family Name
The common plant family name according to Jepson.
For readers that prefer a more comprehensive guide, sorted by scientific name, please download the “wild plants” version of this
guide.
