Asclepias verticillata (Whorled Milkweed)

Asclepias verticillata, commonly known as Whorled Milkweed, is a rare, slender, upright perennial characterized by its fine, thread-like, whorled leaves and delicate clusters of small, white, star-shaped flowers. This drought-tolerant native plant has a graceful, airy appearance, making it a versatile addition to prairies, meadows, or pollinator gardens. It serves as a host plant for monarch butterfly caterpillars and provides nectar for a variety of pollinators.

Asclepias verticillata thrives in well-drained, sandy, or rocky soils and is highly drought-tolerant, making it an excellent choice for xeriscaping and low-maintenance gardens. It requires minimal care, with occasional deadheading to encourage tidiness and self-seeding for naturalization. This milkweed pairs well with other drought-tolerant plants like Coreopsis, Echinacea, and Rudbeckia for a vibrant and ecologically beneficial display. Its flowers attract a wide range of pollinators, including bees, butterflies, and hummingbirds, while its leaves serve as a critical food source for monarch caterpillars. Deer- and rabbit-resistant, Whorled Milkweed is a resilient and valuable addition to sunny borders, wildflower meadows, and naturalized landscapes.
