Hector, I'm a newbie here too, and having lots of fun with all the nice people on the forum.
I love white daylilies, and I think your seedling no.6 is my favorite
. I don't have Ice Age Frills, but I do have Voila Francois, which is brand new in our garden this year. All the photos I saw of it before I bought it were showing it as very white. However, here ours seem to be like yours, more of a cream color. Nevetheless, it is a beauty, and I have a photo of it. You might be interested in checking it out for your breeding program. Oh, yes, your pink seedling no. 3 is my favorite of the pinks, but all your seedlings look pretty impressive. Good luck with your DL program, and hope to see you as a "regular".
VOILA FRANCOIS
