Daylilies can take 3 years to mature. Blooms can be spot on right from the get go and some can take 3 years to match. I have experienced that. So for now it could be considered close enough and a daylily you would keep your eye on. As long as it is pretty to you and makes you happy. Now if you wanted it for hybridizing that would be a different story. Many blessings to you on this wonderful day!
