With over 70,000 named varieties and thousands of seedlings out on the market, there really is no way of knowing what the name is - unless you have a list of what you bought and are trying to match them up. That sometimes happens if tags get broken. Some daylilies have very unique blooms and those we might be able to guess at, but even then it's just a guess. If someone takes a guess and its the wrong name, that is not the best thing if you ever give them to someone - the wrong name can get passed around as they in turn give them to someone etc.
Do you have any other info - height they bloom at, diploid or tetraploid, early, mid, or late season, where they came from, even how long you've had them or who ever you got them from had them?
