Swamp Milkweed

Asclepias incarnata

Perennial flower

The pink milkweed. A tidy, upright plant that stays where you plant it — no aggressive runners like Common Milkweed — with clusters of small dusty-pink flowers that draw butterflies from across the yard.

Notes on growing

Give it a wet spot: a rain garden, a low corner, the edge of a downspout, or plant it and water generously the first season. Emerges late in spring — leave a marker.
