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.
