Symphyotrichum laeve (Smooth Aster) [20 Seeds]
Germination Information: There’s conflicting advice about germinating smooth aster, so I recommend it only for gardeners who enjoy experimenting. I have not grown this species from seed myself—I just let my plants self-sow as they like—so I can only present you the options.
One approach is to surface-sow the seeds 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.
It is also possible that these seeds could germinate in 2 to 3 weeks if you sow them in warm, moist, bright conditions. But if you try that and no seedlings appear after a month or so, then provide an artificial chilling period of about 2 months.
Note that this information will not be on the seed packet you receive.

Smooth aster (Symphyotrichum laeve, formerly Aster laevis) is a lovely option in an outstanding genus of perennials for the fall garden. With upright stems typically reaching 2 to 4 feet tall, it fits easily into beds and borders; it adapts to a range of soil conditions; and it’s usually not bothered by powdery mildew or other fungal diseases. The clouds of lavender-blue flowers appear in September and October, much to the delight of butterflies, and they combine beautifully with goldenrods (Solidago) and fall-colored deciduous trees and shrubs. The species is native to much of North America; these seeds are from wild plants growing in my meadow in Bucks County, PA. Full sun. Perennial; Zones 3 to 8.
Collected in early November 2022. At least 20 seeds. PA ecotype.
