It could very well be that they bred these themselves. We do have a few unregistered daylilies in the database but I only allowed them as they were widely distributed and I found lots of online vendors carrying them, including several daylily exclusive nurseries. I made note of them in our database that they are unregistered.
I would leave this particular series out for the time being as these do look suspiciously as renamed ones, especially that Starburst® Susie Evergreen (Hemerocallis x 'Monie'). It reminds me of
Daylily (Hemerocallis fulva 'Kwanso')
especially this part of their description "naturalizing at woodland's edge." It's sterile so they couldn't have bred it
If they become more widely grown, someone will eventually propose adding them and then we can deal with it.
