David,
Zone 7 or so here, right next to the Ohio River. I keep gingers and plumeria, amongst other things. Unless the plumeria are blooming, I leave them potted and take them to the basement when the night temperatures hit the mid 40's. If they are blooming, they come in to a sunny spot in the house until its time for their nap. Sometime in late February/early March, I'll bring them up to get them started. Basically the same with the gingers, once their done blooming, they dry for a bit and then to the basement. My plummies do fairly well, my gingers have done well in the past, but I missed a cold snap back in March that did quite a bit of damage. Most have recovered. Once their in the basement, an occasional misting and constant vigilance to keep them from getting too dried out.
