I'm always interested with comments that Historics have survived and that today's fancier ones may not. I'm certain there were many bred during the historic period that were not vigorous and no longer exist. Not all historics were good growers. I'm also certain that there will be many of today's iris that are good growers and will be around for many years. Just because an iris has wide parts, substance, ruffles and lace, and intriguing colors doesn't mean they are weak and questionable as to good growth.
