I picked up this edition in a used book store at our local library. It starts with a brief introduction followed by a glossary that describes the various parts of wildflowers. After this there is a short description of each wildflower including it's Latin name and where you will most likely find it in North America. Yes, it does cover Canada. The number of each wildflower description matches the picture (plate) in the book. She then follows up with a 'Ready Identification Chart' for the more savvy flower enthusiast.
The down side to the book are the plates are very colorful but the pictures are not crisp and clear. In some cases they are slightly blurred. The book is large. It is not something I could see you taking in the field to identify wildflowers. Also, you have to page back and forth to read the description and then look at the picture. These 'cons' knock off one star.
So why four stars? Because if you don't mind the negatives it is still a nice book to have. I could see someone that wanted to frame the pictures. Mixed media artists would enjoy using this book as a reference point. Beginning gardeners will take pleasure with identifying a plant growing in their yard. Lastly, any students of botany would find this a keeper. For now my copy sits on the book shelf with other garden books that I don't want to be without.
