From Flora of Indiana (1940) by Charles C. Deam
This species prefers dry, sandy soil and has escaped from cultivation to roadsides and pastures throughout the state. It has become a weed in some of the eastern states, and I have seen large colonies of it in Indiana in sandy soil in pastures. It is difficult to eradicate and, for this reason, should be exterminated as soon as it is detected. It is commonly called butter and eggs.
