Very fine, with great pictures and identification tables in the back that help you tell the difference between similar varieties of weeds. In fact, it's the best book I've found for identifying weeds. My only complaints are that it's a bit scientific and dry, and garlic mustard - a very destructive weed - is not included.

Great book for the homeowners and horticulturalists. Great pictures and descriptions. The weed "Bible".

This book is a treasure. I own and use many dozens of "weed" and plant books and this is one of the most comprehensive and useful. The written presentation for each plant includes information on its propagation, seedlings, roots, flowers and fruits and habitat, and more. The photographs are excellent and show the habit, seedling, leaves, flowers/fruits and seeds. Some grasses are also included.

I hope that the authors will eventually expand the geographical coverage and the number of species. I'll be first in line to buy a new edition!
