Swamp Milkweed

Swamp Milkweed is listed botanically as Asclepias incarnata. It may also be listed as pleurisy root, Rose Milkweed, Pink Milkweed. Swamp milkweed is a moisture-loving North American perennial with pink flower clusters that support monarch caterpillars and many nectar-feeding insects. It belongs in sunny rain-garden edges, moist borders, and pollinator plantings. Do not present it as a food or home remedy; milkweeds contain biologically active compounds and are best treated as wildlife plants rather than edible crops. PlotPal's canonical care record lists full sun and higher water needs. The current taxonomy reference places it in the genus Asclepias and in the family Apocynaceae. Its source-backed growth habit is listed as forb/herb. PlotPal currently carries Swamp Milkweed as an outdoor growing and flower reference.

Propagation or sowing note: Cold-stratified seed, division, or nursery transplant Plant-health prevention note: Maintain airflow, avoid prolonged waterlogging around the crown, and remove severely diseased debris after the growing season.
