Whorled Milkweed

About Whorled Milkweed

Whorled Milkweed offers a delicate, fine-textured aesthetic that contrasts beautifully with the broader leaves of other prairie plants. This slender perennial grows 1 to 2 feet tall and is characterized by its narrow, needle-like leaves arranged in whorls around the stem. In late summer (July to September), it produces dainty clusters of fragrant, greenish-white flowers that provide a late-season nectar source for bees and butterflies. Native to a variety of habitats including prairies, fields, and open woods, it is remarkably resilient, thriving in full sun and dry to medium soils. Despite its dainty appearance, it is a tough plant that spreads via rhizomes and is toxic to livestock, making it deer-resistant. It serves as a valuable host plant for Monarch caterpillars, especially later in the season. Whorled Milkweed is easy to grow from seed and often benefits from a 30-day cold stratification period to ensure successful spring germination.
