It appears to be one of the crested irises. Tectorum, maybe? I'm not at all familiar with the crested species, though, so I'm just guessing.

Good eye, laurief. I GoogleImaged "Iris Tectorum," and a photo of I. tectorum looks just like what I got.

I'm going to disagree. I. tectorum has standards more like a bearded - these are too open. I. tectorum also has a hairy crest/beard almost like a bearded iris, but much thinner and narrower. I don't see that here. This looks like i. japonica to me, especially the foliage. I. japonica has that open face look and the non-hairy crest.
