I once had 'Batik', which eventually died on me (possibly from either extreme of over or underwatering). I was actually relieved. I didn't find the flowers all that attractive, and I like my irises taller, anyway. If it had not dumped me, eventually I would have dumped it.
I have a vague recollection of having had another broken color iris at some point (this was before I started recording everything on the computer), in muddy yellow and burgundy, but that one got dumped. I guess I simply do not like "variegated" flowers (as opposed to variegated foliage).
A couple of years ago I almost got rid of 'Hidden Surprise', for the fault that it was shorter than, and not as showy as, 'Arctic Express' (the only other white iris that I had at the time). I relented at the last moment and kept a few rhizomes, which bloomed half-heartedly this spring. We may yet part ways.
