Asclepias incarnata 'Cinderella' (Swamp Milkweed)
Outstanding native that grows to about 4-5' tall and produces blooms of pink with an unusual cinnamon/vanilla scent in summer. 'Cinderella' has paler pink flowers than the straight species. One of the very best plants for attracting and supporting not only monarchs but a long list of native butterflies. Likes sunny moist settings. Deadhead for repeat blooms. Makes a great cut flower.
