1 Gallon Pot. Native. Asclepias incarnata, commonly called swamp milkweed, is a native plant found in swamps, river bottomlands and wet meadows. It typically grows 3-4′ tall (less frequently to 5′) on branching stems. Small, fragrant, pink to mauve flowers (1/4″ wide), each with five reflexed petals and an elevated central crown, appear in tight clusters (umbels) at the stem ends in summer. lowers are very attractive to butterflies as a nectar source. In addition, swamp milkweed is an important food source (albeit somewhat less important than upland species of Asclepias) for the larval stage of Monarch butterflies.
