Ethnobotany Used for stomach and intestinal pains, for diarrhea, as an expectorant, for heart trouble, taken for lung troubles, as a laxative, for rheumatism, as an aid in child birth, taken for swellings, for cuts, as a tonic, and as a ceremonial medicine. It is now known that it should be approached with extreme caution due to the presence of cardiac glycosides.
Description A stout milkweed with very showy orange or yellow blooms. Found throughout Southeastern and Central Arizona in habitats ranging from wetlands, to disturbed roadsides, and openings in oak woodlands. This plant tends to die back to an underground tuber in the winter so good drainage should be provided to avoid rot.
