Swamp milkweed (Asclepias incarnata) produces clusters of fragrant, pink flowers in mid to late summer atop 3- to 5-foot-tall stems. This U.S. native naturally grows in moist to wet soil but can adapt to average garden conditions. Like common milkweed (A. syriaca), swamp milkweed serves as a food source for monarch butterfly larvae, which feed on the leaves. The flowers also attract a variety of adult butterflies, as well as other pollinators. Unlike common milkweed, swamp milkweed tends to stay in distinct clumps, so it can be a good option for smaller gardens. Full sun. Perennial; Zones 3 to 8 or 9.
Collected in September 2022. Provenance is Bucks County, PA (seeds are from wild plants growing in my meadow, so PA ecotype). At least 20 seeds.
