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 small, 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. The seed pods, smaller and more sharply pointed than common wilkweed, will persist long into winter.
