It needs to dry out in winter anyway... when it's dry, it can tolerate quite a bit of cold. And a cool, dry jolt is really necessary to initiate blooming, I think. Since it has been indoors all this time, probably not a good idea to blast it with sudden heat at this point (it would be fine if it gets to gradually build up to summer). But once it starts to cool off a bit in the fall, putting it outside until night temps are down into the low 40's F may get it thinking about spring flowers.
