From Flora of Indiana (1940) by Charles C. Deam

Infrequent to frequent throughout the state except in the northern tier of counties. It grows in moist or wet soil in bare places, and, where it is found, it often forms large colonies. My notes say "abundant over an acre or more in acid soil in a one year old, fallow cornfield in Warren County," and "abundant over more than an acre in moist, sandy soil in a fallow field about 2 miles northwest of Monticello, White County." It is most often found in old logging roads, about old hog wallows, and on the borders of dried-up ponds.
