A portable, comprehensive field guide--brimming with concise descriptions and stunning color photographs, and designed to fit into your back pocket--from the go-to reference source for over 18 million nature lovers. This guide covers 80 of the most common native wildflowers of the East--species that anyone is likely to encounter. Our geographical range is bounded by the Atlantic Ocean on the east, and on the west by the 100th meridian, extending from Edwards Plateau in Texas northward through Oklahoma and westward through eastern Colorado, Wyoming, and Montana, and Canada, along the eastern foothills of the Rocky Mountains. A companion volume covers flowers west of the Rockies.
