Leona Heights Wildflowers

A photographic guide to showy wildflowers of Leona Heights Regional Open Space

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.
