This unique milkweed is one of Illinois’ 24 native milkweed species, although it lies at its westernmost extent in our state. Showy clusters of aromatic, bicolored flowers atop unbranched stems for about a month each summer. The central stem is greenish to purple and complimented by its interesting leaves, which are glossy-green and long with wavy edges. Common in high-quality woodland openings or edges, thrives in dappled sun. Host plant for the monarch butterfly.
