This species has only recently appeared in this state, and, no doubt, in time will become an obnoxious weed at least in the southern part of the state. I first found it in 1931 in a 3-acre hogyard and it covered at least a fourth of the area. Hogs in the yard did not feed upon it. It is a native of the southern states and is introduced northward.
