If you bring it inside it will probably croak, these are very much outdoor plants. They hate being inside but can handle very cold temperatures no problem so long as they are kept dry. Damp cold means rot. They don't really grow during winter, but the roots do and once spring comes they explode! A word about heat though, they can survive temperatures over 100 F but once it gets over 85, they must be in shade (dappled light, or morning sun only are best) or they will cook. You can tell when it is getting too warm for them when they start looking lopsided, half of the plant will start growing taller on one side in an effort to shield itself from the hot sun. Here's a picture of what they look like when it starts getting too hot.
