Asclepias verticillata (Whorled Milkweed) [15 Seeds]


Germination Information: I recommend these seeds only for gardeners who have experience with seeds that benefit from or require a chilling period. The easiest approach is to surface-sow, or just lightly cover, the seeds in a pot in fall to late winter, setting them outdoors in a spot protected from mice so they can get a natural chilling period and then germinate when conditions are right in spring.

If you sow after February, give the pot an artificial chilling period of about 2 months.

Note that this information will not appear on the seed packet you receive.

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.
