Not sure why this has become a frost aster. Because it's more fun than old field aster? Easier than hairy white oldfield aster? An attempt to get rid of the confusion of all the combinations of the last? Or because in their profusion, they kind of look like frost, and are liable to bloom until frost comes. Frost aster is common in a variety of open habitats in AL, AR, CT, DE, FL, GA, IA, IL, IN, KS, KY, LA, MA, MD, ME, MI, MN, MO, MS, NC, NE, NH, NJ, NY, OH, OK, PA, RI, SC, TN, TX, VA, VT, WI, WV, BC, NB, NS, ON, and QC(L).
