This gorgeous blossom is undergoing a rebranding effort in the name of monarch survival. Commonly referred to as Swamp Milkweed, the plant is one of the essential natives for monarch caterpillars. In an effort to encourage more gardeners to embrace this beneficial plant, the new moniker lends a more delicate, desirable image. This is no swamp plant: it’s Rose Milkweed (thank you very much).
