Asclepias incarnata, or Swamp Milkweed, has pretty rose-pink, long-lasting fragrant flower clusters on upright plants. This perennial is sought out for its nectar-rich blooms and its leaves are larval food for monarch butterflies.
Native to all but the westernmost United States, Asclepias incarnata is naturally found in sunny wet areas such as river bottomlands, wet meadows, and swamps.
Asclepias incarnata prefers sun and moist to wet soil, but tolerates drier conditions and clay soil. This plant does not respond well to transplanting. Asclepias incarnata is a favorite plant for monarch butterflies and their fans.
