David Lionberger had this note and photo in the latest Lincoln Iris Society Rainbow Messenger.  Thank you David for sharing this.

Much to my surprise, as I was working in our iris beds, I
noticed there were bloom stalks on Peach Jam. Gary White
gave us this 1989 Ensminger tall bearded iris about four years
ago. It has performed well in previous years but had never
re-bloomed before. There are two large stalks with several
buds each. May blossoms have competition for September
blossoms on this one!
