I'm looking for a book or books which will help me learn to identify common plants in the Northeast and across the US. Is there a single resource you can recommend for someone interested in this? Multiple books?

Any other tips on learning plants would help...

thanks.

I also like to ID plants. My absolute favorite is North American Wildlife published by Reader's Digest. My mom had one while I was growing up, and I had to get one for my own family. Not only does it identify N. American plants, but also wildlife,birds, mushrooms, mollosks, ferns, trees, whatever. I can't think of a time it has failed us.
Good luck!
