Climbing Hempweed (Mikania scandens)

Climbing Hempweed (Mikania scandens)

The only climbing Composite. It twines around bushes and forms a tangle of green leaves intermixed with pretty pink clusters of flowers. They have a way of lying flat over the tops of other bushes, forming areas of deep pink. As the flowers grow old, they become pale and ragged. They can be seen in almost any wet place on Long Island, in New Jersey, to Kentucky and southward, keeping rather near the coast. The leaves wilt quickly after being picked.
