Sorry, maybe I didn't explain that well.....
AHS is the only International Cultivar Registration Authority (ICRA) for daylilies. Miss Amelia and your daylily from a Dutch hybridizer are not registered cultivars if they are not recognized with registration through AHS. To be considered a registered daylily cultivar... the registrations must go through AHS following the registration guidelines otherwise both daylilies are considered unregistered.
