To all, my wild growing Iris from way back to 1964 is not the same as 'Plum Quirky'. Sorry to add my photos and draw attention to my Wild Iris. Notice the more yellow in the bottom falls. Mine is more solid brownish.

I moved your images to the generic iris entry.

In the future, if you ever find that you need to propose a move to another entry or remove an image, just enlarge your image, scroll down and you'll see where those options are located. Follow through and hit submit and it puts in into admin's queue for approval.

Thank you Suzanne,
Looking carefully at both picturs, I could see I made a mistake. They are so very similar.

There are so many thousands of iris, the only way you can ever be close to making an ID is to grow a suspected ID rhizome side by side. IDing thru photos rarely works.
Since it's so old, maybe try posting it in the Iris Forum, we have a Historic thread there and lots of collectors of oldies, they love a good mystery! They may come up with a possibility.

Suzane, Way back when I first joined, I showed pictures of this and nobody knew about it. I simply gave up.

That happens, it stumps every one! Well, it's a sweet one and it seems these historics are resilient. Enjoy!
