Swamp Milkweed is a perennial plant native to North America. The plants are used especially in gardens designed to attract butterflies. The nectar of the plant attracts many other species of butterflies and insects as well. The plants are also sold as freshly cut flowers, mostly for their long-lasting flower display, but sometimes, for the distinctive seed pods.

The plants bloom in early to mid-summer, producing small, reddish-pink colored flowers in rounded clusters, or umbels. We also offer the soft-pink flowered version of this plant Red Milkweed (Asclepias incarnata).

Swamp milkweed prefers moisture retentive to damp soils in full sun to partial shade, and typically in the wild is found growing wild near the edges of ponds, lakes, streams, and low areas-or along ditches. It is one of the best attractors of the monarch butterfly, which feeds on the flowers and lays her eggs on the plants. The emerging caterpillars feed on the leaves.
