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.

Cold stratification required: direct sow in fall or early winter into a clean, prepared bed. Or, for spring sowing, sow in deep seed-starting pots about ¼" deep, in rich, damp soil. Cover and refrigerate for 3 weeks. Afterwards, move to a 70-degree, well-lit spot for germination, which can take up to 14 days. Transplant outdoors after frost in a moist to average soil area that can remain a milkweed patch for years.
