Yosemite is one of the crown jewels of our national park system. Although the park is most famous for its magnificent peaks, domes, and waterfalls, it is also a treasure trove of wildflowers due to its incredible diversity of plant habitats and its extensive elevation range.

This is the first comprehensive Yosemite wildflower guide that's small enough to fit in a book bag. The guide was designed to help people identify almost all the wildflowers that grow in Yosemite. The only flowering plant categories not included are grasses, sedges, and rushes, along with trees and shrubs that have inconspicuous flowers.

Over a thousand species of wildflowers are covered in the book, either individually or in similar plants sections. The plants are organized first by flower color and then alphabetically by family. Flowering time, habitat, vegetation zone, and elevation range are provided, and interesting information is included for many of the plants. The book provides a glossary of botanical terms, a general index, and a family index. The family index lists all the plants covered in the book in alphabetical order by family.

Barry and Judy Breckling began studying and photographing plants in Yosemite in 1994. Since 2007 they've lived in the Central Sierra Nevada foothills, not far from Yosemite's Big Oak Flat entrance. They previously lived in Henry W. Coe State Park, where Barry was a state park ranger for 30 years.
