swamp milkweed

Asclepias incarnata (swamp milkweed) is a moisture loving plant native to North America that thrives in swamps, marshes, bogs, fens, and open areas.

The deep pink flowers are attractive to pollinators, especially monarch butterflies who lay their eggs only on milkweed plants. A. incarnata will grow 2-4 feet tall and produce small, deep pink flowers. The seed pods will persist into winter, providing an appealing cool season visual.
