I agree with Zuzu. As long as the pots are large enough for them to keep growing, if you have a sunny window, they should be able to hang on until spring. Insects may be a problem, and dry air can make insects infestations worse, so be prepared to shower the leaves off occasionally.
I have a friend from Latvia who says she grew pansies year round there! Wish we could do that!
She also had incredible roses and clematis there.
