I have a mystery daylily that looks a LOT like the one in your picture, but might be just a bit more on the purple-red side versus orange-red (although it varies by day). Does yours occasionally have more of a blue-ish (kind of purple-red) cast sometimes, too? Do you happen to have a picture of the whole plant? Mine only measures about 22" or so, but was in shade where it was originally growing until I purchased it 2 weeks ago, so it's possible that might have affected its height, I think. Your answers might help me solve this daylily riddle once and for all!
