Symphyotrichum novae-angliae seeds will usually germinate in 10-14 days. Sow seeds about 2mm deep in a Well drained seed sowing mix at about 20°C.
Stratification (cold treatment or vernalization) Some seeds need to be overwintered before they will germinate. Some seeds need just a couple of weeks, others 3 months. Seeds can be stratified in dampened peat or sand, in a plastic box or bag at 4°C or 5°C in a refrigerator. The seeds should not be frozen or in a wet medium. Very small seeds can be sown on the surface of their growing medium, in pots sealed in plastic bags, and kept in the 'fridge. Many vernalized seeds need light to germinate when they are sown in the "Spring".
