I have seen daylilies that are registered by a name, and then 'trademarked' and sold under an entirely different name altogether. And also anyone can hybridize a daylily, and name it and sell it w/o registering it at all. Often times plants get passed along w wrong names by mistake, wrong plant tag, or spelling error. Or people don't know the name of the plant so they make something up to have something to use in reference to it. Many people buy sell or trade daylilies they purchase and may not even realize that daylilies ARE registered or that AHS even exists. I dind't know for several years after I had started growing them. Also the AHS database is SUPER picky and if you mis-spell anything or if your name is all one word instead of 2 ect, it doesn't pick it up so you don't know it exists. The search feature doesn't work well.
