Char,
I just pulled up those over 2228 listings with some form of the word pattern in the description, of those listed I am guessing maybe a fraction of a percentage would actually fit the new AHS description of a patterned daylily.

I would expect that term to be used exponentially more now that it has been recognized and defined? Will it be possible to narrow down a search to fit that term so the non relevant things like eyes, and appliques will not be included?
