Peterson Field Guide Of Eastern and Central North America. by Lee Allen Peterson

I love this book, its small enough to be taken into the field with you, its details are really good, but there are two things about this book that take it from a well done edible plant book to a must have.

a), They have a section on what to look for in each area you are in, so if you are in a swampy area, you look up in the swampy area to see what is most likely to grow there, which brings about

b) they tell you what is typically found per season in each area, with a note for the plants pages to go look things up.

Each plant has a list of what can be done with it. If you want to do any kind of foraging, I would recommend this book for your shelf..
