The strong, erect, purplish stem of Indian-hemp rises 3-4 ft., with branches ascending from the upper part. Long oval leaves often have a white coating or bloom as found on plums. Small cream-colored flowers are clustered at branch ends or on stalks from leaf axils. Tufted seeds form in spindle-shaped pods.
Women of some tribes rolled dogbane stem fibres on their legs to make fine thread, said to be finer and stronger than the best cotton thread. It was used for sewing and for making twine, nets, fabric and bowstrings. A number of varieties occur across the continent. This species can become a serious weed as it is aggressive and difficult to control.
Once thought to be a larval food for Monarch butterflies, research has shown that while adult female Monarchs will occasionally oviposit on this species, their offspring will not mature on it.
