Perhaps someone will know it. I am sure there are thousands of Iris hybrids out there. I have eight plants (actually probably 20 plants, but in eight pots) with flowers just like that pictured, and the plants were salvaged from a house that was being torn down. They were then brought to me in garbage bags for me to "save" them, which I did. I seem to have a reputation for bringing plants back from the dead, LOL.
