Unless you have a very warm winter, I doubt they'll live through if you leave them outside, Margie.
I tried to pot them up and bring them in when we lived in Utah. I'd call it "marginal success" because they lived, and grew nicely again when it was warm enough to go out in the springtime but they weren't any better than if I had just let them die and buy new transplants in the spring. I did have nice sunny south-facing windows, but they didn't bloom indoors all winter.
So in retrospect it was quite a lot of trouble for very little return, I think.
