My favorite daylilies are white. These are all my personal pictures. I included a couple of "creams" also.
Kennesaw Mountain Lemon Sorbet (Beautiful, but very slow to increase), but I love it anyhow.
Early Snow - fantastic
Joan Senior - the whitest I have
Margo Reed Indeed - very white also - (A very good replacement for the frustrating Heavenly Angel Ice - they look the same, but this one is much more hardy.)
Voila Francois - love it
Boundless Beauty
Karen Leigh - Love it
Gaskins Seedling - Victorian Lace x Voila Francois
White Star (not a registered name - just what I call it) - love it, just as white as Joan Senior
Westbourne Snow Cream - very white also
Jammin's Magnolia Bell
Whiter Shade - could not find my picture
Swiss Mint
Anna Irene Polston
Isabelle Rose
Ice Milk
Heavenly Angel Ice (I just sold this one as it frustrated me - way too fragile of a plant!)
