This is usually an attractive and elegant plant. It is the only milkweed in Illinois that favors wetland habitats. Swamp Milkweed is easily distinguished from other milkweeds (Asclepias spp.) by its erect umbels of pink flowers, tall branching habit, and relatively narrow leaves. Other milkweeds with pink flowers, such as Asclepias syriaca (Common Milkweed) and Asclepias sullivantii (Prairie Milkweed), are shorter and less branched plants with wider leaves. Sometimes stray plants of Swamp Milkweed occur in drier areas; these specimens are usually much shorter and little branched, but their leaves remain narrow in shape. Return
