Funny you brought this up and I don't have an answer for you, but I have a ton of Lychnis cornonaria germinating in my garden now. Usually the seeds don't do this until spring. It must have something to do with our odd weather this year.

I think I would find a spot close to your should & cover with leaves for the winter.

Hey with this weird weather we are having, there easily could still be 6 weeks or longer until the ground freezes hard. I would wedge the pot in against the house foundation on the south side, surround with soil, cover with ground-up leaves, and wish it well.

Then I would plan on winter sowing some more. If you need more seeds, I'd be happy to send you some.

Thanks guys, I think I will try to keep the germinated seedlings outside and protected and try to winter sow more. I know my son loves this plant and would like one for his garden. Vignewood

aach... I bet those lychnis coronaria (rose campion) will do fine - mine survive winter in low teens last year and stayed green. Hope yours does too.

Many perennials germinate in the fall and then ride through winter...they will have a better survival rate if they have snow cover, but should be just fine.
