Oh Alice, they are so easy to keep indoors in Winter! I keep mine, in bloom, or not, in a WSW living room window. Just a spritz everyday, and they hangout with all my others. Phals, Catts, Dens, Oncs....They do very well! Reconsider! They are very adaptable!
edited to add this photo, of last year...I've since added a few more that will hang out here as well...
