Can you tell us where you have the plant indoors, light direction (north, south, west, east), your watering regimen and the ambient temperature around the plant.
Typically the plant does not mind being in its container for a long time, seems happier actually, but it does prefer to be on the dry side, since it has such thick roots, so your planting media has to be very well draining too.
I got mine to bloom in late winter, after I gave it a cool dry rest for in late Fall. Temps then was at the range of 50 to 55F. Then I brought it indoors in January. I like this plant, so low maintenance and always lush looking as long as kept in shade and on the dry side.
