Well technically it is a tropical perennial. I grow them outdoors and have never tried bringing it in for the winter. Maybe you have inspired me to try. But I'm thinking to stay alive indoors it will need supplemental light (even if you have a really good south facing window, we just don't have enough hours of daylight in winter) and frequent misting, to counteract how dry our houses are in winter. If you are willing to work at it like that, you could give it a try, but I wouldn't expect it to bloom even so, unless you have high intensity lighting and
really work at it. Otherwise, you would just be keeping it alive so that next spring it would be ready to take off.
Since you inspired me, I may dig up my giant one when it starts getting cold and cut it way back and bring it in.... Dunno . I collect seeds from it, but most of the seeds don't ripen up until the very end of the season, sometimes even after first frost. So to cut it back and bring it in in time, I would be sacrificing some of the seeds. Still thinking.....
