You are correct ,Paul. The ones that were "miffy" growers didn't make it "back in the day", either. And there are hybridizers incorporating some of the "old' genetics, though back crosses, to beef up the hardiness of their new creations. Still, it makes one wonder if the "historic" iris everyone is hunting for, and not finding in the year 2075, Might be something like "That's All Folks"! As time passes, and styles and desires change with it, who knows what we will choose to protect, pamper, and preserve, and which will be allowed to "fend for themselves" ? That page of the book has yet to be written, but I do think it's up to us , In the Here and Now, to do our best to preserve, and protect, love , and pass along ALL the ones we can, with their names, and pedigrees....so those who come after us can ponder these same things, and say to themselves ,"I wonder!?"....Arlyn
