This is the reason that I am a firm believer that you can't ID a NoID unless you had a list of what daylilies you owned, and somehow the tags were lost. If someone moves to house where there are daylilies growing, and they want to have someone ID them - I think that is just impossible.
There are SO many that look similar.
One might register a "look alike" because it has better bud count, or the scapes are better branched, or it performs better in your area.
