Respected Botanist and Author William Carey Grimm presents easy-to-follow keys, finely detailed illustrations, and expert descriptions for accurate identification of wildflowers and native shrubs in this authoritative guide. Study the shape of leaves and the arrangement of any flowers, then turn to page 20 if it's a wildflower, or page 339 if it's a shrub. In winter, use key VI on page 360 to identify leaf-losing shrubs.
