”sdlg” is used in daylily data to signify unregistered or unlisted parentage (seedling crosses). This has been a non-issue for me in the past, but I am bumping up against it a little bit now in my research while planning crosses.
Do I now care?
No. I am a hobbyist. I am focusing on fun and maybe a dedication project from time to time. I don’t ever see a day when lack of daylily parentage information would cause me to not use it in a cross. In fact, for the Mahala project, both daylilies in that (hopefully successful) cross don’t list any parentage at all. It actually fits the project to a “T” – a lot of unknowns. And that is ok.
