strange iris

Is anyone familiar with this Iris? The weird thing is that this plant is producing two different varieties. It has this flower and purple flowers too.

I am wondering if it bloomed without the other petals or something ate the other petals and this is just the inside.

I think so. Looking to the left you can see where the standards were attached. There either is cold damage or something ate the petals.

Slugs.

Do you have a photo of the purple one. The veining is very pronounced on the falls. How tall is it and how large is the bloom.

Another one should open soon.
