Answer: Tuberose Begonia's thrive in filtered shade, rich, moist soil, and humid air. If yours refuses to bloom, it's not getting quite what it needs. If you've given it all the proper conditions and it still won't bloom, a little pinching back should encourage new growth and new flowers. Sometimes you need to stress a plant just a little bit to make it bloom. Try holding back on the fertilizer (too much nitrogen makes lush green growth at the expense of brightly colored blossoms). Hope it stops behaving badly and rewards you with gorgeous blooms.
