I don't see that listed as a registered cultivar(with that spelling) with the AHS. Who hybridized it?
Edited to add:
It's a beauty, must be a future registration
Good eye Kent. Schreiner's did apparently make an error because their photo for 'Prairie Splendor' is the same exact photo at the AHS page for 'Prairie Spirit', same color description and seedling number listed too. https://www.schreinersgardens.... https://www.daylilies.org/Dayl...
