Hi Larry - I recognize you from around ATP, and I think from Cubits too - I replied to your "form" thread.... but welcome here to the daylily forum! It's funny how after years of gardening, you can become interested in a plant. I know you are an accomplished gardener! I am glad you finally became interested in "America's Favorite Perennial" ...
I enlarged your photo and I must say that I don't know that I have ever seen a white edge on the sepals like your seedling has. Edges, either dark or light, on sepals are usually only there if they are on the petals too. You have a good eye to notice that, and to recognize that it was different.
Did your seedling just come up on it's own? In all my years in daylilies, almost 30 now, I don't think I have ever had that happen, although they say it happens with the plant Stella d Oro. I thought I had a mystery seed come up in between the aisles once. I let it grow, and it bloomed in just 2 years. Was a LOVELY color with watermark. I was so excited. Until I went to Curt Hanson's the next summer and then recognized it there as One More Heartache - which had been planted nearby. I must have broken enough of a root and crown off when digging it to sell, then smushed it into the ground accidentally with my foot or something, so that it took root and grew. We still laugh about that.
I usually recommend a new person visit a display garden or two near them before they start really buying many daylilies. Talk to the owners, find out what plants to really well. Get an idea what types of plants are available, and see the colors in person. Here is a link to an article I wrote for last year's daylily week, telling about display gardens, and how to find one near you.
