Swamp Milkweed

Certified Organic

Asclepias incarnata

Support butterflies with this summer-blooming beauty!

Large, rose-colored clusters of flowers, smelling fragrantly of vanilla, sit atop upright, branching stems. Although usually a swamp plant, this milkweed grows surprisingly well in medium, regular garden soil. It is a great addition to any perennial wildflower garden, rain garden or shoreline planting. Blooms July-August.

An excellent nectar source for visiting insects including butterflies, bees, wasps, ants, flies, moths, beetles and bugs. A host plant for larvae of the Monarch butterfly. Because the goal is to foster genetic diversity, plants will not necessarily be uniform and there will very likely be natural variations in color, size, and growth rate.
