Dylan, down here they are grown everywhere, from full sun to full shade, but as Donald points out, the best color seems to be on plants that get maybe half a day's sun.
In the summer here, it spreads by creeping along the ground and rooting at the leaf nodes. It can become a pest if not contained. For you, cold winters will take care of that problem but be sure to bring some cuttings, or a pot of the plant indoors to keep it going for next year.
