Iowa has chosen this wild prairie rose for their state wildflower. A very nice choice, particularly because it is easy to distinguish from all those other wild roses. Wild rose flowers look very much the same. But this one has leaves with nine to eleven leaflets. The others push to get to seven. Prairie rose can be found in AR, CO, IA, IL, IN, KS, MA, ME, MI, MN, MO, MT, NC, ND, NE, NM, NY, OH(X), OK, SD, TX, VT, WI, WY, AB, BC, MB, ON, QE, and SK. Sedgwick Co CO, 6/16/13.
