Symphyotrichum pilosum (Frost Aster) [20 Seeds]


Germination Information: I recommend these seeds only for gardeners who have experience with seeds that benefit from or require a chilling period.

One approach is to surface-sow the seeds in a pot in fall to early 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 technique works great for these.)

If you sow after January, consider giving the pot an artificial chilling period of about 2 months.

It is also possible that these seeds could germinate (though perhaps at a less than optimal percentage) if you sow them in warm, moist, bright conditions. But if you try that and no seedlings appear after a month or so, then try the artificial chilling period.

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

Frost aster (Symphyotrichum pilosum or Aster pilosus), also known as hairy white old-field aster or awl aster, flowers in fall, with a super-abundance of small, white, yellow-centered blooms on branching, woody stems that can reach anywhere from 3 to 4 (or even 5) feet tall. Native to much of central and eastern North America, it is one of the many “little white asters” that grow wild here at Hayefield. Over the years, I’ve found several seedlings that have bright yellow splashing on the basal foliage, often extending up into the flowering stems, and I call them ‘Hayefield Variegated’. Despite my being very careful to collect only from the best variegates, it seems that the seeds don’t often produce variegated offspring. So, figure that these seeds, which I collected from several plants of ‘Hayefield Variegated’ as well as around a dozen wild plants in my Bucks County, PA, meadow, might produce a couple variegated seedlings but are most likely to have the usual green foliage. Be aware that frost aster can self-sow freely. Full sun to light shade; Zones 4 to 9.

Collected in late October 2022. At least 20 seeds. PA ecotype.
