If you want blooms try 'Dragon Wings'. The best bloomer ever but the leaves are on the dull side. 'My Special Angel' has beautiful spotted leaves and seems to bloom most of the summer but doesn't get very big. 'Silvermist' is a huge cane begonia with silver streaked leaves and light pink blooms and is hard to beat. 'Irene Nuss' is very much like 'Sophie Cecile' but without the silver streaking and blooms very well. There are so many other good blooming canes that you will just have to buy some to try them. Most canes will bloom given the right conditions of light and fertilizer. They do best outdoors for me but I do have some sporadic bloomers indoors as well.

Good luck.
