Great seedlings, Mona. My favs are the red ones and the SC Cranberry Kid seedling. I saw three blooms in your photo. I'll bet it would be awesome in a big clump. You asked if I had noticed differences in color. I really haven't noticed any difference. What I have noticed is a decrease in bud count on nearly all the daylilies this year. I don't know if was the very warm weather, followed by freezing temps or if it is because I set too many pods on them last year.
Actually, come to think of it, some that never set pods for me still have a lower bud count. I have used the same fertilizer regimen, except this year i did not use Epsom salts. I read somewhere, maybe on ATP that it can affect colors in daylilies. I am sure yours are enjoying all the special attention you have given them.
