Glen, that one just GLOWS. Love it. I myself am, not into pastels, but yellows and corals that glow, now that is a different story.
As for seeds - if you purchase seeds, you get to register any that seem worthwhile. Doesn't matter who hybridized the seeds.
If you are looking to add some genetics not found over there across this big pond, then yes, pick up some seeds - have you checked out the LA - the daylily auction? Some sellers only sell seeds within the US, but others will make the effort to ship overseas.

As for the genetics/ parents of that seed - if it is unknown, that is how the plant is registered. I have older daylilies - that 5 decades ago were registered, but I have no clue the names of them - any seedlings I get from them would be registered as unknown. I also have bee pods - that I know the pod parent, but have no clue of the pollen parent - so 1 would be identified, the other parent would not be.
I know that in the US, it is relatively inexpensive to register a daylily ~Jan
