Asclepias tuberosa (Butterfly Weed) [20 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 sow the seeds, barely covered with growing medium, 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. (The winter-sowing approach works well for this species.)
If you sow after February, give the pot an artificial chilling period of about a month.
It is possible that these seeds could germinate (though perhaps at a less than optimal percentage) if you start them in warm, moist, bright conditions. But if you try that and no seedlings appear within 3 weeks or so, then try the 1-month artificial chilling period.
Note that information will not appear on the seed packet you receive.

Butterfly weed (Asclepias tuberosa) is a type of milkweed that produces clusters of vibrant orange flowers in summer atop 1- to 2-foot-tall stems. The foliage turns yellow in fall, complementing the slender, red-blushed seedpods. Like common milkweed (A. syriaca), this US native serves as a food source for monarch butterfly larvae, which feed on the leaves. The flowers also attract a variety of adult butterflies, as well as other pollinators. Butterfly weed grows in distinct clumps; no worries about it spreading like some other milkweeds can. These seeds are from wild plants growing in my meadow in Bucks County, PA. Full sun. Perennial; Zones 3 to 9.
Collected in early October 2023. At least 20 seeds. PA ecotype. Shipping to US addresses only.
