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.

Please read the description as well before ordering.
