I just visited 1/2 price books website and saw a book offered on "weeds". sorry I can't remember the exact name. I ordered a book on "propagagtion".

'The Gardener's Weed Book' by Barbara Pleasant
great book!

Don't know of any books, but there is a website that's divided by region. I've listed it below.

Here is a link that might be useful: Weed Web Site

Thanks soo much for the weed site. Jody

Hi! I recently got a used book on Ebay called "common weeds of the united states" Prepared by the agricultural research service of the United States Department of Agriculture. No color pictures, just drawings and text but it seems to me to be quite informative. It is also offered new by the Dover Books company. Hope I was helpful.

I've found "Weeds of the West" to be one of the best references for identifying natives (and other people's natives.) The book has clear color pictures, and though it focuses on "weeds" that interfere with farming and grazing, some of them are our favorite garden plants.

A little spendy, but I've really used mine a lot.
