Your daylily seedling looks to be as white as Gentle Shepherd and that is very white indeed. For me, Gentle Shepherd is the whitest daylily that I have ever seen in person. I remembered seeing it in the garden of Perfect Perennials in York PA and remarking that it was even whiter than President Ronald Reagan and Sunday Gloves that were bloomed at the same time.
In my garden, GS is very white by mid afternoon.
