Ditto on everything roby said, though I've let a couple of plants get down to 33-34 F (1 C) outside in the fall and spring and they didn't seem to mind. I do keep them drier when it's that cold, though. If you're in a mild climate area of the US you may be able to grow this species outside year-round.
Also, I've had new growths blast from watering in conditions without good air movement. This was mostly an issue with one plant indoors for the winter, another one outside right now has new growths and is watered 1-2x/day without any problems.
Congratulations, this is a wonderful species!
