Thank you both! Interesting how varied the difference between tets and dips can be in different plants. I'm sure you know that tall bearded iris are now almost exclusively tets. The difference in tets vs. dips in bearded iris is amazing.
I'm looking to buy some more daylilies now that I've seen what beautiful new daylilies there are. And I was wondering if I should look at ones that are tets or dips. So you've answered my question.
