Hybridizing for blue has been part of our program since we started and something that really peaked Ashton's interest in daylilies. I currently have several hundred seedlings from parents with some blue appearance in the blooms. Several seedlings have been blooming in our gardens and starting next spring there may be 500 or more seedlings with blue eyed parents. I have posted some of the seedling in past seedling threads but here are some examples:
Also using Little Blue Angel, Blue Flirt, Dixie Blues, LW Calico Blues, Crystal Blue Persuasion, in diploid program.
LW Calico Blues
Little Blue Angel
Blue Desire, Margaret's Blue Diamond, Texas Blue Eyes, Blue Wrangler, in the tet program.
I have one other trait that I am using to get to blue, that is watermarks crossed with blue eyes.
