I don't grow this daylily, but
Harmon Hill Farms has this listed. I think they said it was sold out, but it might be worth checking with them, if no one has it to help you out.
Longlesson daylilies also has it listed (for a very reasonable price, it looks like) as well. And Lasting Dreams Daylilies had it on a price list. I didn't see their list on their site currently, but again, would be worth contacting them if none of these other options don't pan out.
Good luck
