Hi Sue,
SWAMP DUST happens to be one of my favorite daylilies and I would say that I'm almost positive that the photos I submitted are SWAMP DUST. I have had this plant in my garden for at least 3 years. Since I have never seen this plant in person I could have been sent the wrong plant and not have realized it. I'll try to find some other pics of it but for now why don't you leave out those photos.
Thanks,
Karin
