Any ideas as to what cultivar this might be? I am sure it is a historic iris. My husband and I built our home 25 years ago on the site of an old farmhouse that was torn down in the 60's. Our neighbor (who has since passed away) had grown up in the farmhouse from the early 1900's. The irises were planted around the house by his mother or grandmother. There were only a few when we moved in. They had been mowed down for years. Now I have a large patch and have transplanted them throughout the yard. Any help would be greatly appreciated. Thanks in advance.
