I've just purchased 3 planters of impatiens to use as decoration on my deck. I'm pretty sure that (strangely) nothing on or in the containers mentioned the variety of impatiens, but my googling has made me pretty sure that they are a fuschia New Guinea impatiens. In any case, I'm interested in growing these plants as perennials, but the winters here in New Hampshire are cold and very snowy. Will impatiens grown in planters do well indoors during the winter? Would they require special care (lamps, heat, etc.) or could they be kept as houseplants and simply put back out on my deck in the spring after the last frost? Thanks for any responses - I have never tried growing "outdoor" plants indoors during the winter.
