Most of my daylilies have come from a guy who used plastic tags tied around the base of the fan for all the DL he sold once a year. The kind he used are similar to the tags you find on fruit trees that are soft plastic "hang tree tags" and can stretch a little as the plant grows. They are long rectangles with a hole in one end so you can loop it around the plant and through the hole like a zip tie (but wider and softer plastic). It looks like on Amazon you can get 250 tags in different colors for $12. The sharpie writing did fade over time, but it should last long enough to evaluate your seedlings. When the fans started to multiply I would cut off the tag with a knife or scissors.
