Red Milkweed belongs to the wet places — the boggy seep, the pond edge, the rain garden that never quite dries out. Native from New Jersey south through Florida and west to Texas, it is a plant of the sandhills and swampy pine savannas, and it carries that character with it into cultivation. Growing 2 to 3 feet tall, its stems rise from reliably moist, acidic soil in full sun to partial shade, topped in June and July by tight clusters of pink to pale purple, star-shaped flowers that are something close to irresistible to bees and monarch butterfly larvae alike.

For the gardener willing to work with wet soil rather than against it, this is a plant of genuine purpose. It serves as a larval host for monarch butterflies and produces the distinctive milkweed seed pods that split open in late summer, sending silky-tufted seeds drifting on any passing breeze. The stems contain a milky latex sap — gloves are advisable when handling. In bog gardens, along stream banks or pond margins, or wherever water lingers after rain, Red Milkweed brings a wildflower energy that the landscape quietly needs.
