Right now in Sibley, one is reminded that it is wild rose season. These are prairie or climbing rose. They can stand alone or clamber over other shrubs. Once thought rare in Michigan, but now more often recognized. The rare perception may well have been because of the difficulty many observers have in separating the species. Actually, prairie is one of the easier ones, with only three leaflets and that columnar pistil. That pistil is actually a bunch of pistils united to form the column. The only other like that here has white flowers. Most wild roses just have a lump of pistils that show their anthers right at the spot where the petals meet. Some populations of prairie rose have flowers that get lighter or almost white as they age. It's a nice show!
