Asclepias incarnata 'Cinderella'

Swamp Milkweed

Asclepias incarnata 'Cinderella' commonly called swamp milkweed, is an erect, clump-forming cultivar of the Missouri native plant which is commonly found in swamps, river bottomlands and wet meadows throughout the State. It typically grows 4-5' tall on branching stems. Soft pink flowers appear in tight clusters at the stem ends in summer. Stems exude a toxic milky sap when cut. Flowers are followed by attractive seed pods which split open when ripe releasing silky-haired seeds easily carried by the wind. Flowers are very attractive to butterflies as a nectar source. In addition, swamp milkweed is an important food source for the larval stage of Monarch butterflies.
