This is a tightly twisting vine with no tendrils which grows to be about 6 feet long. Its fuzzy, sweet scented flowers are about 1/8"-1/4" wide and have bulbous tubes at their base. The smooth leaves are 1/2"-1 1/2" long. It can be found climbing on boulders, fences, over forbs, trees and shrubs in the South Texas Plains and Edwards Plateau regions of Texas as well as a few other areas in juniper shrublands shrubbery, at upper edge of wooded canyons, and on dry rocky limestone slopes. It oozes latex when injured as do other members of the milkweed family. It is the host plant for the Variegated Fritillary butterfly.
