I just re-read the end of my post, wondering why I also didn't get an acorn for bringing up the topic of the ploidy. (Lol, just kidding (sort of).) I must have been half asleep posting it because I used the word "dormant" instead of "diploid" in the third sentence of my last paragraph (where I was questioning what the ploidy really was).
(I actually did mean to check the children, to try to determine what the ploidy "should" be, but got distracted and then came back and posted without doing further checking.)
Anyway, thanks Julie for your clarification. I am glad to see that there is a consensus that 'Mary's Gold' is a tet. The blooms do have a very long style... perhaps that is part of my problem with not setting pods.
I would love, love, love to see a daylily with blooms of this exact same size and color, on the same height scapes, but which are a bit fancier/rufflier/fuller.
Off to correct my previous post...
