OH, YES< I know exactly what you are talking about now, I think I only have one like that. Bread and Wine. would LOVE to have more, I didn't even know that dalylilies HAD those lovely glittery edges until it bloomed last summer for me.
I don't know if there is an 'official' name for that glittery edging or not.
The glitter sprinkles over the petals I have always refered to as diamond dust, totally different.
