I've had this iris for several years now and this year I moved some of them to my backyard. They surprised me by reblooming! (Only the ones I moved to the backyard.)
Through looking at pictures online I thought it might be Crimson King, fits the description, but it's so hard to get a good picture depicting the reddish purple color! They are only about 26"-28" and very fragrant.
