This is another where there are two daylilies under the same name. There's an All American one and a registered one. The All American may be a trademark so not really an accepted name. I had a quick look for a plant patent but didn't find anything - I'll look more thoroughly later or maybe someone else might search the uspto. If it's just a trademark then the cultivar could be anything. A trade designation should not be in single quotes because it is not a cultivar name. The registered 'Frankly Scarlet' is a tet. I believe the All American daylily sold under that name is a dip but I'm going from memory and haven't yet verified that. I guess another database entry that needs amending, presumably again the rust rating applies to the non-registered one.
