They will not survive, if you keep them outside in pots. I tried it once,
they got
too much frost to their roots. Luckily I had propagated them before, so it
wasn't
a total loss. If the pots are too big for inside, you could plant them
outside just for
winter and put them into pots again in late spring.

Thanks...I was thinking this morning that I'll have to bring them in.
The current blooms did get a touch of frost one night when I forgot to
cover them up. I think they enjoyed being outdoors for the summer, but
I didn't realize they would be so delicate!

Best,
Christine
