Propagation Notes Smooth Blue Aster
Stratifying Symphyotrichum laeve
Information on stratifying Smooth Blue Aster seems to vary. I have had sucess by either sowing outdoors in the fall or cold moist storage starting in November. I would imagine 30 day would be plenty but we find it easier to stratify all of our seeds at once. However, I should mention that stratified seeds are checked once a month. On occasion they have sprouted while in cold storage. If this occurs use a pair of tweezers and gently plant them into your cells. Keeping them moist and out of direct sun for a few days will improve your success rate.
Next to a quarter are a dozen young Smooth Blue Aster seedlings.
