Hedychium coronarium, variously known as White Butterfly Ginger, or where I live just White Ginger.

Unfortunately, I don't think you'll have much luck keeping it in check AND getting it to bloom. You can do one or the other, but it blooms a lot better with a fair sized root mass. You could try confining it to a big pot, but it'll bloom better in the ground.

Thanks Lisa. Guess I'll just have to live with it where it is. As I mentioned, my yard is postage stamp size, and I'm afraid it will overtake the house, if I'm not careful. Wonder if I can just hack off some of the shoots from the original mass as it gets bigger. Sure to love the smell.
