Irises: This iris jumped into my wagon and I don't know what it is, 1 by Equilibrium

I was at a RoundUp and a friend of mine spotted this Iris when we were checking out at The Flower Factory. It didn't have a tag and I thought she said it was a Siberian Iris of some sort. She knows her Siberian Iris pretty well and it doesn't look like a Sib to me so I'm thinking she was referring to the other one next to it which was a Sib. I bought them both but this one didn't have a tag. Any ideas which Iris it might be?
