Like most milkweeds it contains toxic chemicals, and can be injurious to livestock when eaten green or as a dry contaminant in hay. Milkweeds are the foodplants of the Monarch Butterfly and other species in the family Danaidae. A perennial broadleaf plant that can be found in almost any moist or dry situation. An extremely deep taproot allows it to survive in very dry situations. Growth is from seeds, or from creeping underground roots. The seeds have long, silky tufts of hair at their upper end, and when released by the wind may be carried long distances. Seeds germinate in the spring, along with regrowth of foliage from the roots, and the plants mature throughout the summer, with foliage dying in cold weather.
Perennial with regrowth from spreading roots. Seed dispersal in the wind may carry seeds long distances.
