Swamp Milkweed
Swamp Milkweed is vital to the survival of monarch butterflies — the preferred host plant for monarch caterpillars, producing the milky sap that both feeds the larvae and makes them toxic to predators. This showy, 2–4 foot native perennial produces beautiful clusters of small mauve flowers filled with nectar that attract dozens of butterfly and pollinator species throughout the summer season. Growing swamp milkweed is one of the most meaningful and ecologically valuable things any gardener can do for local wildlife.
