This fully revised edition brings a new level of beauty, accuracy, and usefulness to the field guide that wildflower enthusiasts have relied upon for more than 20 years.

More than 940 all-new, full-color images show the wildflowers of western North America close-up and in their natural habitats. The guide has been completely revised to make identification in the field easier than ever. Images are grouped by flower color and shape and keyed to clear, concise descriptions that reflect current taxonomy.
