Honeyvine Milkweed has heart shaped leaves, shiny seed pods and white, vase shaped flowers that bloom in clusters of five. The vine grows ten to twenty feet in length and when the seed pods are mature they split open to release brown oval seeds that have a tuft of silky hair attached to one end. I helped to release a lot of these seeds as a child. It has been recommended by beekeepers as a good source of pollen for honey production. Monarch butterflies will feed on this plant although it does not have the milky sap like that of common milkweed.
