Pink Milkweed

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.  More information about Swamp Milkweed can be found on this blog post.
