I know nothing whatsoever about Daylilies. But from your description, I think it means that this particular one is your "own creation." If that be the case, is it possible that you might still have a couple of seeds from this particular flower? It is exquisite! I've learned from our friends at N.G.A. that Daylily flowers do not come true from seed, but if it were possible, I would love to try with this one.
I know we just had an amazing seed swap. But this is a possibility that I would not want to miss...if it IS a possibility. It is just beautiful!
God Bless You;
