Several years ago when I had a greenhouse I managed to get it to flower.
 During the winter I kept the medium much drier than normal, keeping it moist
rather than submerged.  Temps were near freezing, to about 5 deg. C (41 deg
F).  By June I had the plant at the level pictured by Loyd.  Hope this helps.
