I've never tried it myself, Ann, but I know there are people who do, at least with the Gingers. The key is warmth. People up north who have the best success at this have greenhouses. That way they can keep the plants warm and humid with lots of light even through the worst weather of winter. You want to give the plant the closest thing to a tropical environment that you can. So, with that in mind if I were going to try to grow these in a cold-winter area like yours, I'd plan to overwinter them in a sunny window as house plants. They may not keep blooming but they will keep their nice foliage if your house is 70ish daytimes and 60ish at night.
You simply can't expect any of these plants to grow when the weather is cold. They go dormant if night temps go below 50, and take weeks to recover. If, for example, you pushed it a bit in the spring, and had a late cold snap, you might get only half as much bloom over the summer if that happens.
