What are the coldest temps that Dahlias can take? I was wondering if they could be used for winter bloom the way we use pansies here. Do they stop blooming when the temps get too cool or the days grow shorter?

This spring I planted out some 'Figaro' dahlias that I had grown from seed. Since we'd been having summer droughts the past couple of years, I decided to plant them in a low-lying area. But this year we had rain and more rain, and that area stayed waterlogged far too long. Some of the dahlias died. A few have made it, but don't look nearly as nice as they did before the rains started.

I wanted to start some more seeds now and have them ready to go out (in a different area of course) when the weather begins to cool. Based on your post, I think it just may work. No harm in trying. I can always replace them with pansies if they don't make it.
