Peterson's Field Guide to Wildflowers: Northeastern and North-central North America
A field guide is necessary for positive identification of wild plants, and this one is our favorite. It is an excellent resource for most of the country, and the one we find the most useful here in the Southeast. It's organized by flower color and number of petals.
"Find what you're looking for with Peterson Field Guides—their field-tested visual identification system is designed to help you differentiate thousands of unique species accurately every time. Grouped by color and by plant characteristics, 1,293 species in 84 families are described and illustrated. Included here are all the flowers you're most likely to encounter in the eastern and north-central U.S., westward to the Dakotas and southward to North Carolina and Arkansas, as well as the adjacent parts of Canada."
