Apocynum androsaemifolium, the fly-trap dogbane or spreading dogbane, is a flowering plant in the Gentianales order.
The plant is common in North America, and is widespread across most of the United States and Canada, and in Alaska, California, and northeast Mexico.[1][2]
Description
Apocynum androsaemifolium has branching stems, hairs on the underside of the leaves, and no hair on the stems.[3][4][5] Milky sap appears on broken stems.
Leaf margin is entire and leaf venation is alternate. Its leaves appear as pointed ovals, while its flowers appear terminally on a stalk.
The plant is poisonous[6] due to the cardiac glycosides and resins it contains.[7]
