I am also looking for a vintage variety of iris to replace some very sentimental ones I just lost to iris borers yesterday. I had a "Melanie" variety that I received from my grandmother that she bought nearly 75 years ago, and moved through 3 states, and She gave me some rhizomes and I have moved them twice. I found they were infested with iris borers yesterday and lost all but a very few. I'm heartbroken because grandma's house has been sold and there is no way to replace them from her.
