Asclepias syriaca (Common Milkweed) [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 surface-sow (do not cover) the seeds 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. (I’ve gotten great results using the winter-sowing approach with these seeds.)

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 artificial chilling period.

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

Common milkweed (Asclepias syriaca) produces stout, upright stems usually 4 to 6 feet tall, with clusters of fragrant pink flowers in summer. It can spread vigorously by creeping rhizomes but is worth growing in an out-of-the-way spot as a host plant for monarch butterfly larvae. This US native also attracts a variety of beneficial pollinators. It’s so important to grow this plant, wherever you can. These seeds are from wild plants growing in my meadow here at Hayefield in Bucks County, PA. Full sun. Perennial; Zones 4 to 9.

Collected in late September and early October 2023. PA ecotype. At least 20 seeds. Shipping to US addresses only.
