Asclepias incarnata, commonly known as Swamp Milkweed, is a native perennial wildflower found throughout much of eastern and central North America. This upright, clump-forming plant typically grows 3 to 5 feet tall and produces fragrant clusters of pink to rose-purple flowers in mid to late summer. Unlike some other milkweed species, Swamp Milkweed thrives in moist to wet soils, making it well suited for rain gardens, wet meadows, and low-lying areas. It is a critical host plant for Monarch butterfly caterpillars and an important nectar source for a wide range of pollinators.

Swamp Milkweed thrives in full sun and prefers moist to wet, well-drained soil, though it will tolerate average garden moisture once established. It’s ideal for rain gardens, pond edges, wet meadows, and pollinator plantings where soils retain moisture or stay consistently damp.
Swamp Milkweed typically grows 3–5 feet tall and 1.5–3 feet wide, forming upright clumps with narrow, lance-shaped leaves and tall flowering stems. It adds height and structure to wildlife gardens, native borders, and wetland restorations.
Swamp Milkweed blooms in mid- to late summer (usually July through September), producing large clusters of fragrant, pink to rose-colored flowers that are highly attractive to pollinators. It may rebloom lightly if deadheaded.
Yes—Swamp Milkweed is a host plant for Monarch butterfly caterpillars and a nectar source for a wide range of pollinators, including bees, butterflies, and wasps. It’s one of the most important native perennials for supporting Monarch conservation efforts.
Yes—Swamp Milkweed is deer- and rabbit-resistant. Its milky sap contains toxic compounds that make it unpalatable to most herbivores, helping it persist in landscapes with browsing pressure.
