I really have no problem with the "30 year" division for "Historic".....although there *may* be OTHER words that would be more descriptive, depending on an individual's viewpoint...."pioneer iris", for all those that first found homes in someone's garden....maybe "historic", meaning those that were important in breeding, color breaks, form, etc.,........."classic", for those that best display "our" ideal in form, and color ( but most of us have quite different tastes !)......"has beens", for those that always want "the latest and greatest"....although "old fashioned" could be used here, as well. I guess, for me ,the "name" we put to them doesn't really matter.....I could quote Shakespeare ...as much as the concept BEHIND the name. I, personally, can't understand how what was ONCE considered a beautiful thing, can ever be "forgotten".....but that's just me, I guess
