Prickly fanpetals is up to around two feet tall, with flowers a little under an inch across. If you draw a line from Texas east all the way to India you can tell where the species transitions from native to the south, and weedy to the north. Here it is mostly introduced, sometimes classified as a noxious weed. It has reached as far north as Michigan only rarely. It's been reported three times, twice near Detroit, and once here in Lenawee County. That collection was from along a railroad in the little town of Britton in 1920. The seeds were probably dropped in activity around the grain elevator. The plants did not persist. That record is kind of typical for the northern limits of this plant.
