Description
Whorled milkweed (Asclepias verticillata) looks very much like Arkansas bluestar (Amsonia hubrichtii) in leaf, spreading by rhizomes to form patches of slender, unbranched, 1- to 3-foot-tall stems holding whorls of slender, rich green leaves. Clusters of greenish white flowers bloom in mid to late summer. Like other milkweeds, whorled milkweed serves as a food source for monarch butterfly larvae. The flowers also attract a variety of pollinators. Native to much of the US, east of the Rocky Mountains. Full sun to light shade; average to dry soil. Perennial; Zones 4 to 9.
Seed collected in September 2021 is sold out. I hope to collect again in 2022.
