Could it be Iris uniflora or Iris minuto-aurea? The latter in particular is 
famous for not flowering. There are other small irises from the same general 
area (Korea, Manchuria, eastern Siberia, etc) that are notoriously difficult to 
flower, though in their native habitat they put on a respectable show. Or so I 
gather - why else would anyone bother collecting them, plus, you can't get 
seeds to collect if the plant doesn't flower.

Another possibility is that it's one of the very dwarf forms of Acorus 
gramineus. Some of these have been known to masquerade as irises, the game only 
being given away when a clever gardener persuades them to flower.
