Asclepias incarnata, also known as swamp milkweed, is often found in wet soils throughout the state, but does well in drained medium soils. An ideal plant for a downspout rain garden, this is one of the host plants of the migrating monarch butterfly. While Asclepias syriaca seems to be preferred by the insect, A. incarnata is still frequently utilized.
Seed pods turn brown and rupture in the fall, exposing numerous seeds each connected to a single tuft of silk, which are readily carried away by the breeze.
The genus Asclepias comes from Asklepios, the Greek god of medicine.
