This showy native perennial is valued for its long bloom season, upright habit, and exceptional value to pollinators. Swamp milkweed brings reliable summer color and strong ecological benefits to home gardens, especially in sites with consistent moisture.

Rounded clusters of fragrant pink to rose-purple flowers bloom in mid to late summer atop sturdy stems. The flowers are rich in nectar and highly attractive to butterflies, bees, and other beneficial insects. Narrow, lance-shaped green leaves give the plant a clean, vertical look that fits easily into mixed borders and naturalized plantings.

Well-suited for home gardens, Asclepias incarnata thrives in full sun to part shade and prefers moist to wet, well-drained soil. It tolerates periodic flooding and is easy-care once established, making it a dependable option for rain gardens, pollinator plantings, and low areas of the landscape.
