Milkweed is the common name for perennial, herbaceous plants of genus Asclepias, family Asclepiadaceae (from Greek physician Asclepius). One hundred species occur worldwide; 13 are native to Canada.
Common milkweed is a widespread wildfower. Also native in North America, it's a common wild sight in almost the entire eastern two thirds of the continent. In early summer, the thick stems are topped with large, pink, fragrant flower clusters. Big nectaring insects like bumblebeesgo nuts over these blooms.
