It seems this may be the incorrect ID, it does not resemble Winter Memories; your bloom has narrower petals and doesn't have the ruffles or green throat as registered.

No reply here so image has been moved to the generic daylily entry.

Sorry, Sue, I didn't see your comment/question until just now. I concur. Thank you for moving it. I think the one in that picture that was 'Winter Memories' was the daylily in the background (not visible in the thumbnail). I wish I knew which daylily the one in the foreground actually was...

Anyway, thank you for your attentiveness!

That's exactly what I thought, it was the one in the background!
These older classics have an elegant beauty that you just don't see in newer cultivars.
