Here is a photo of the group of yellow daylilies, Frozen Jade, Mary Todd and Happy Returns, in my garden. In this photo, you can see the buds for Frozen Jade in the foreground, and they are very green, then you see Mary Todd in the mid ground, and she has the yellow buds with the black tips. Happy Returns is shorter and only seen a bit on the right hand side. Carolyn Criswell is the daylily in the background.
