Jackky wrote to say he meant "Single" by 'Full Form'. So at least we know he is asking for our best wide white edge on a single form daylily. That is something I have not really paid much attention to, but I did a search of my plant list and only came up with three single form daylilies that had a white edge: However none of them actually had a wide white edge.
I have only seen one daylily with a wide white ruffle edge and that is Pray Without Ceasing. Another is Carolina Pale Face. I have seen more daylilies with a white toothy edge than a ruffle or chicken fat edge.
