Hello!

I am pretty new to seed starting. About two weeks ago, I started some purple coneflower, viola tricolor, bellflower, and aster seeds under lights, on a heat mat. I have gotten quite a few sprouts from the first three, but none from the asters. I have some seeds in a damp paper towel in the fridge that I will try if these don't germinate. These are Wonder of Staffa aster seeds. Does anyone have much experience starting asters from seed? What should I expect?

Thanks!

Sarah
