Almost impossible to tell from a photo; there could be many that look just like this. You could try using the advance search in the database and include color, eye zone color and "midrib". But don't hold your breath. It looks identical to my first cross, which has never left my yard, so I'm sure it is not one of those, no matter what the resemblance

Requests for ID should include other data for best results--height, size of bloom, blooming period, possible origin, etc.

There are over 100,000 registered daylilies and many that look alike, especially in a photo. I wouldn't venture a guess because that is exactly what it would be especially without any other data as Mantis mentioned. My advice is to enjoy it without a name. All of us have NOIDs in our garden that we keep because we like the flower.

Roger that, Nancy. My favorite is a NOID, but Rosie Cottons Ribbons may take first place; it bloomed for me yesterday for the first time, and I love it!.
