I did work with an albino seedling for over a year, but found that even with all of the careful feeding of it (see the article) it could not gather enough energy to stay ahead of the trimming I had to do in order to keep it going. So, I was not able to get the seedling beyond the nascent-root stage. Since it would be necessary for it to develop to the crown stage in order to sustain itself with nutrients from the soil, I finally gave up.
As Maurice indicated, there are some known albino-recessive cultivars that you can cross if you want to get a lot of albino seedlings to work with. Three named daylilies are identified as being albino-recessives in an abstract at

Good luck to any who try it ... some day when I have a lot more time on my hands, I will likely try to get one to the developed-crown stage to verify whether the mature roots would indeed get the necessary nutrients from soil. I'd love to see an albino daylily bloom if that were achieved!
