You could also go to historiciris.org, look at the picture gallery tab, then enter some search criteria on the right of the screen. That might help find something sooner. Hopefully it is a registered variety, not a result of a bee pod.
Looking around the yard and iris beds I found an oddity, one last bloom showed up while Mohave Gold is still in bloom:
Nassak, HP Sass, 1939, a "midseason" bloomer
