Julie,
someone made a comment in the database entry that this doesn't quite look like Spacecoast Royal Rumble, not the same color and your edges show more of a ruffled gold rather than the fine white edge as the other images show.The suggestion was made that it could be Daylily (Hemerocallis 'Royal Rumble')

Thanks for getting that ID straightened out, easy to get those Spacecoast Royals mixed up!
