Try it with your yard

Honeyvine milkweed is a twining perennial vine that can climb 3-10 feet tall on fences, trellises, or other plants. It produces small white flowers in summer followed by milkweed pods that split to release seeds with silky white hairs. The vine dies back to the ground each winter and regrows from deep roots in spring.
