Hi Sherri, that's a beauty. If you don't know the cultivar maybe you could post it under the Iris x norrisii entry with "unknown cultivar or NoID" in the caption. Species X Iris (Iris x norrisii)
Edited: A search for Pardancanda norrisii should bring up all of the Pardancanda (Iris x norrisii) entries.
