Whorled Milkweed, perennial, is different than many of the other milkweeds due to its very skinny leaves that are “whorled” up the stem and its short growth of only 2 feet. Its July-September bloom period makes it one of the latest flowering milkweeds, providing nectar for many insects while most other milkweed species are setting seed. The white flowers shine in the full sun to partial shade that it prefers to grow in. A native to most of the eastern 2/3 of the United States, Whorled Milkweed inhabits open areas of upland prairies, meadows, pastures, ditches and waste areas where it can spread through rhizomes to create small colonies. All parts of the plant are toxic to livestock and humans, although many Native American tribes ingested it for medicinal uses. If the plant is broken, such as having a leaf removed, it produces a milky white sap from the wound.
