About swamp milkweed
A native perennial growing 3'–6', with fragrant deep-pink flower clusters in summer and 5" seed pods in fall. It's the larval host for monarch and queen butterflies, the only plant their caterpillars can eat. Also draws bumblebees, honeybees, tiger swallowtails, hummingbirds and more.
Growing details
Light: Full sun, part sun
Mature plant height: 3'–6' (can be kept smaller when planted in a container and by pruning)
Bloom time: June–August
Bloom color: Pink, lilac
Soil moisture: Damp to wet
Soil type: Acid, neutral, rich, average, clay
Spacing: 1'–3' on center
Native to Michigan, it adapts well beyond wet habitats and tolerates dry spells, heavy clay and most soil types once established. Good for rain gardens and pond edges. The roots run deep — plant it where you want it to stay. Expect a few seasons before it's really showy; spacing plants at 1' gives a fuller look sooner.
Companion plants
Damp-to-wet conditions: white turtlehead, common boneset, Joe-Pye weed, soft rush, great blue lobelia, blue vervain. Drier conditions: purple coneflower, rattlesnake master, smooth oxeye.
