Is it a seedling or a sport of a named variety? Whatever it is, keep an eye on it. There are several who are working with variegated daylilies, but it is a hard job. Many don't seem to be very vigorous or else they revert to green.

Its just one of regular daylillies that started doing this. I dont know how it happend. Probaly a nutrient defiancy I am guessing? I just thought it looked cool

Variegation in plants has nothing to do with nutrients or deficiencies or soils, etc. It is caused by cell mutation and can be random or inherited/genetic. The last tends to be stable, the first not stable. It can also be caused by a virus and that tends to be stable as well.

Since yours appeared randomly, I would not expect it to show up again next season.
