Thanks, Juli, for pointing our attention to Char's article! And many, many thanks to Char for all of the invaluable info in that piece! Since the form was only registered in 2010, it would be very time-consuming to determine which registered cultivars prior to then have (some of) the genetics that developed sculpted daylilies. It's great to have an historical sketch that gives clues about which cultivars - registered prior to 2010 - contributed to a new form.
In my own garden, I was pleasantly surprised to see Salter's "Moon Over Monteray" (a superb cultivar because it's an EMO and not rust-prone) show a distinct sculpted relief form, though highly dependent on the temperature. Some of its progeny also have this form, but it isn't easy to figure out whether it was specifically some part of "Moon Over Monteray's" ancestry that passed on this trait. Thanks much for the detailed ancestry info! : )

PS Like Lyle, I'm curious about AHS' requirements for registering a sculpted seedling. "Moon Over Monteray" looks great even if temps don't reach 70 F degrees in the day. But, it's only when it's warmer that sculpting occurs.
