Swamp Milkweed

Swamp Milkweed (Asclepias incarnata)

Swamp Milkweed (Asclepias incarnata) is a native, moisture-loving perennial known for its clusters of fragrant pink flowers and its essential role in supporting pollinators. As a host plant for monarch butterflies, this vibrant wildflower is a must-have for pollinator gardens, wetland areas, and rain gardens.

Distinctive Features

Swamp Milkweed produces upright stems adorned with narrow, lance-shaped green leaves and topped with dense, vanilla-scented pink flower clusters that bloom from mid to late summer. This species thrives in wetter conditions compared to other milkweeds, making it ideal for rain gardens or pond edges. The seed pods split open in fall, releasing silky seeds that are dispersed by the wind.
