Good info on the Swamp Milkweed is here. “As a tall herbaceous moisture-loving perennial, Swamp milkweed seeks sunny openings of swamps, marshes, bogs, fens, and open areas along stream banks and ditches. This robust and erect stemmed plant grows three to five feet high, and like its common milkweed cousin, exudes a milky juice when broken.”
“Swamp milkweed’s smooth narrow leaves are lance-shaped with sharp tips and occur in pairs. Sometimes the leaf’s edges turn inward and upward suggesting the prow of a ship.”
“The fragrant umbelled clusters of flowers range in color from soft mauve to pink to reddish-violet.”
Note: Tropical/Mexican Milkweed (Asclepias curassavica) is controversial among Monarch enthusiasts.
