Richard,
I just happened on your post about ghost train.
The funny thing is that when we moved to Maine last year we had several plants either bought or give to us that I had no idea about. Among them was an Iris that had no name. We were excited every day to check on daylilys, roses and the one Iris to see how they were progressing. I could tell that this Iris was doing well and seemed to like its location.
When the first flower opened I kind of thought OH! I had never seen one that color and to be truthful it didn't overwhelm me. I checked in the data base and discovered that it was "Ghost Train". It is so unique it won me over.
These pictures are from this spring, the first year of bloom
