Apocynum cannabinum
Also called Clasping-leaved dogbane, Common dogbane, Hemp dogbane, Indian-hemp, Dogbane, Prairie Dogbane, American Hemp
Indianhemp is a native North American perennial herb, about 1 m tall, that grows in open woods, ditches and moist sandy or gravelly ground, often near streams. It is grown mainly as a wild or naturalising plant, and its key feature for growers is that every part is poisonous.
Apocynum cannabinum (dogbane, amy root, hemp dogbane, prairie dogbane, Indian hemp, hemp dogsbane, rheumatism root, dogsbane, or wild cotton) is a perennial herbaceous plant that grows throughout much of North America—in the southern half of Canada and throughout the United States. It is poisonous to humans, dogs, cats, and horses. All parts of the plant contain toxic cardiac glycosides that can cause potentially fatal cardiac arrhythmias if ingested. Some Lepidoptera can withstand the toxins and feed on this plant.
