Even though we're surrounded by lakes in Michigan, we don't think of ourselves as isolated. Aunt Lucy might beg to differ. This is a fairly common plant through much of the country and southern Canada. But here it has only been collected twice in two southeastern counties. One of those sites is a nursery, the other a garden, so the plant is not likely a native. I have no idea what accounts for this strange gap in the distribution. Aunt Lucy grows in weedy areas and woodlands in AR, CO, CT, DE, IA, ID, IL, IN, KS, KY, MA, MD, MI, MN, MO, MT, ND, NE, NJ(E), NM, NV, NY, OH, OK, PA(T), SD, TX, VA, WI, WY, AB, BC, MB, ON, and SK.
