That is an arilbred iris. Difficult in some places.
The catalog comes out in Feb. They have 'historic' irises which usually sell out if you don't get them first. Then a good number of tall bearded from different hybridizers, some median & arils & arilbreds. It is well worth a look, espcially when you are looking for different colors for a mixed garden. We have ordered from them for about 10 years.
