I've found several species of gingers called this. Best to use the latin names. Curcumas go dormant every winter and the Hedychiums may, depending on weather.
I grow both in pots. If it's the Curcuma, you want it to be somewhat dryish in winter after it drops its leaves (next year).
They can take full sun if you keep them watered.

I just received this plant from mail order. What side is up on this thing it's bareroot? I think the side wide the bulbs are up just not sure. The instructions were pathetic.
