From Flora of Indiana (1940) by Charles C. Deam
I feel positive that this species was never native to Indiana and I think that our few reports can safely be referred to naturalized plants. I have seen it persist in a fallow field in the Clark County State Forest after cultivation and spread over an area, as nearly as I can recall, of about half an acre in 30 years. I have seen it frequently in large colonies in fallow fields about former habitations. In no instance have I seen it in a place where I would regard it as native and it should be referred to the introduced species. Sargent says: "Probably native in cent. Tex. and Okla."
