On the face of it, all those pink wild roses look a lot alike, which makes them terrific puzzles. Careful examination of the sepals, stipules, leaves and thorns will almost always lead to the right answer. With Virginia rose, the stupules are the final key to identification. Stipules are leaf-like tissue at the base of the petiole. In Virginia roses, that tissue is connected along the petiole, and gets wider as it stretches away from the stem. The sepals also don't have lobes or fringe. If you see rose bushes like that, you will have successfully solved this wild rose puzzle.
