If I keep the multi colored Coleus in a frost free place in the winter, will it come back in the spring?

I have always had these as houseplants and as long as you keep removing the flowers they will be fine. I thik just frost free will be too cold.
welcome to GoY too.

Seaburn's right, if you want to keep it, treat it as a houseplant for the winter, keeping it watered, in the light, and growing. Cut back a bit in the spring and put back outside at the end of May.
