White 40" tall bearded second to bloom very large plants and big cluster here are mire photo trying to give them a name

Hi Robert, and welcome Off the top of my head, the only white one I know for sure is a re-bloomer called "Immortality". Does yours sometimes re-bloom in late summer or fall?

May I suggest you post your lovely pictures on this thread (link below) in the Irises Forum? It's entitled "Show us your NOIDs" and a NOID is an iris with "no ID". That way all the iris experts will see it, and be able to help out.
