Wildflowers of Wisconsin and the Great Lakes Region - A Comprehensive Field Guide By Merel R. Black and Emmet J. Judziewicz

By Merel R. Black and Emmet J. Judziewicz, second edition.  

We've found no other current book in print that is so all-inclusive as a field guide for WI and surrounding states.  For each of the over 1,100 species in Wildflowers of Wisconsin, it includes a detailed WI map (by county) showing where each species has been found, a color photo, and "native/introduced/invasive" status. Some of us at Prairie Moon recall using this field guide as a college textbook. Organized by plant family, it tends to be a favorite resource for those with a little botany knowledge, though it is useful for beginners as well. Shipping fee is included (within the contiguous US).
