Swamp Milkweed
Asclepias incarnata
Certified Organic
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.

Growing instructions
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.
Please note: Butterfly Weed (Asclepias incarnata) is native to much of the eastern and mid continental U.S.—most areas east of the Rocky Mountains. If you live outside of these areas, please do not buy or plant Asclepias incarnata. Before planting any milkweed, it's always a wise idea to reference monarchwatch.org or the Xerces Society for more information on milkweed species that are native to your specific area.
