Keep a Look out For
New Invasive Plants in the Midwest Flyer
Glenn Nice, Weed Diagnostician, Dept. of Botany &
Plant Pathology, Purdue University
Continuing to get the word out about invasive plants,
a new flyer has been developed by the Midwest Invasive Plant Network
(MIPN) highlighting some of the plants to keep an eye out for in
the Midwest. If you should happen to come across any of these
plants, please contact the Plant and Pest Diagnostic Lab at Purdue
University, for there is a need to get a better understanding of
distribution of these plants.
The full flyer with color pictures and written descriptions
can be downloaded from the MIPN
web site (or directly from http://www.mipn.org/NewInvasivesBrochure.pdf)
