The delicate Whorled Milkweed is an attractive 1-3’ft tall perennial with clusters of 10-20 small, greenish-white flowers in the axils of the upper leaves. It is distinguished from other milkweeds by its smooth, needle-like, fine textured whorled leaves arranged on a generally unbranched stem. It prefers full sun and handles dry, infertile soil well. It will grow in richer soils under more moist conditions but spreads quickly by rhizomes, so is best used where colonies are desired. The seedpods are ornamental when they open to release seeds attached to numerous silky white hairs.
Plants range through North America from Canada south to Florida and west to New Mexico. Habitats include upland prairies, sand prairies, gravel prairies, hill prairies, openings in rocky upland forests, sandy savannas, limestone glades, rocky bluffs along major rivers, bluegrass meadows, pastures and abandoned fields, grassy slopes along highways, and waste areas. Whorled Milkweed is a pioneer species that prefers open disturbed areas. USDA Hardiness Zone 4-9.
