Ecological Benefits

Swamp Milkweed (Asclepias incarnata) is a native perennial plant that serves as a vital component of Maryland's wetland and riparian ecosystems. Its pink to deep rose flowers attract a variety of pollinators, especially butterflies like Monarchs, Swallowtails, and Fritillaries. This plant's preference for moist to wet soils makes it well-suited to wetland restoration efforts and rain gardens.


Swamp Milkweed provides essential habitat and nectar resources, supporting the health and diversity of local ecosystems in Maryland. Its adaptability to full sun and partial shade conditions also makes it a valuable addition to gardens and natural areas where wetter soils prevail.
