Swamp milkweed (Asclepias incarnata), a member of the Apocynaceae (Dogbane Family), is a herbaceous perennial that has pink and whitish flowers that bloom in the late spring through to the fall. The leaves have a toxic milky sap that makes the Monarch distasteful to predators.
Swamp milkweed is often found in open wetlands such as wet meadows, swamps, and marshland. It is native to most of North America except for the west coast.
The species name of this plant, “incarnata” is the Latin name for flesh-colored (Lady Bird Johnson Wildflower Center).
