I've tried different things with spotty success. I now use the method many here use. I bury a tag (vertical blind marker using a paint pen) under each of my daylilies. And I also use the clear plastic picnic knives which has a number on it using the paint pen again. I can cross-reference the number to a photo and parentage name. (All mine are unnamed seedlings.) Everything else I tried had limited success. So far, none of the knives have been dug up by critters. Some folks have good success with mapping out their daylilies.... drawing each bed and exact location on a piece of paper of each daylily. Just don't lose your map!!! (I have too many daylilies to do the mapping.)
