It's Big, It's Pretty & I Have No Idea What it Is

Well, I purchased this stunning Hemerocallis with a 'Hyperion' label about 6 years ago. Just before posting, I went onto the net to double-check to see that it is indeed 'Hyperion' - I found all sorts of other photos of 'Hyperion' day lilies that look nothing like this one. So, if there are any day lily lovers out there who might have an idea of what this stunner might be - I'd appreciate it!
