From Flora of Indiana (1940) by Charles C. Deam This species is restricted mostly to southern Indiana where it is usually found in hard, white, slightly acid, clay soil in fallow fields where it is often abundant and usually associated with Alopecurus carolinianus, Myosotis virginica, and Arabis virginica. Since all of my specimens are from fallow and cultivated fields, it seems that one would be justified in assuming that it is being introduced from the area to the south of us. In 1937 it was an abundant weed in an Iris farm near Bluffton, Wells County. …… Indiana Coefficient of Conservatism: C = 0 Wetland Indicator Status: FACU
