From Flora of Indiana (1940) by Charles C. Deam
This species is infrequent to common in all parts of the state. It prefers a slightly acid soil, hence it is infrequent to absent in the neutral soils of the central counties. In the southern counties it occurs in hard, white clay soil and is usually common in fallow fields, on washed slopes, along clayey roadsides, and in moist, sandy and mucky places in our northern counties.
