 Z. mioga has taken temps down to at least -15 in the past ten years in Kansas. It is still there and increasing with some vigor. My variegated form is a sport of my green form and is just as hardy, but slightly less vigorous.

 Jim McK, 

 Alpinia, except the one noted by Tony, need year old shoots to flower. There may be others.

Aaron, when you write " Strangely enough, Alpinia zerumbet has wintered for
two years as a deciduous plant, thus making it not worth growing." 

Does that mean that the sprouts have to be more than one season old to bloom
(I have not grown this plant so I don't know its habits)? 

Kaempferia rotunda survived near a wall here for years, but I don’t think it
ever bloomed. Hedychium coronarium can be grown as a garden plant here, too.
