What leads you to believe your plant is any iris at all? The gestalt of the plant leads me to think it is an iris; it lacks leafy stems like grasses. The leaves are clearly iris-like, the roots are iris-like, without stolons or other grass features. Also, there is no sign of bulbs, corms, rhizomes or other below ground portions that would lead me to suspect membership in other families. Do you have pictures you can post or give specifics? I don't have a flickr or other web image account right now to post pictures. But it is a logical next step to make IDs easier. Thanks for the suggestion. Meanwhile, I wonder if I should increase fertilizer, compost, or do something else to try to trigger flowering next year? Kathleen
