whoops. the review above was for the Weeds of the Northern U.S. and Canada by Royer & Dickinson....sorry, i mis-clicked...
but i also recommend Weeds in my garden: observations on some misunderstood plants by Heiser.
it is highly enjoyable reading and surprisingly well written--fairly unique in the weed readers literature category. he has a real understanding of what it\'s like for us gardeners facing the weeds. it\'s also extremely informative, reliable and definitely great for the weed library. concise drawings, easy to use. A+++
