I don't know if anyone has mentioned Gil Stelter in Guelph, Ontario to you. His garden name is Gryphon gardens. He is one of the foremost experts on Dr. Stout's daylilies in AHS, or anywhere. They grow approximately 60 of Stout's 91 introductions. If he doesn't grow it, perhaps he might be able to refer you to someone who does. If you Google his garden name, his website will pop up and you can contact him from there. Good luck!
These may be some of Dr. Stout's really difficult to locate daylilies, if they were never introduced in Bertrand Farr's catalog way back when. I hope that someone can help you find them.
