Whorled Milkweed

Whorled Milkweed (Asclepias verticillata)

Whorled Milkweed (Asclepias verticillata) is a slender, drought-tolerant native perennial known for its delicate, fine-textured foliage and small, white flower clusters. As a host plant for monarch butterflies and an excellent nectar source for other pollinators, this adaptable species thrives in dry, open landscapes, making it ideal for meadows, prairies, and xeriscapes.

Distinctive Features

Whorled Milkweed produces thin, needle-like leaves that grow in whorls around its slender, upright stems. In late spring through summer, clusters of star-shaped white flowers bloom, attracting bees, butterflies, and other beneficial insects. Unlike many other milkweeds, this species has a more refined, airy appearance and is one of the last milkweeds to go dormant in the fall.

• Soil: Thrives in well-draining, sandy, rocky, or loamy soils.
• Water: Low water needs; highly drought-tolerant once established.
• Humidity: Prefers dry to moderate humidity.
• USDA Hardiness Zones: 3-9, making it adaptable to various climates.

Ideal Uses
