Sweet Autumn Virginsbower (var. terniflora) Clematis terniflora var. terniflora variety

Clematis terniflora is a plant in the buttercup family, Ranunculaceae. It is native to northeastern Asia. It was introduced into the United States in the late 1800s as an ornamental garden plant, and has naturalized in many of the eastern states. It is considered a Category II invasive plant in north and central Florida and some other eastern states, meaning it is invading native plant communities but is not yet seen as displacing native species.
