Years ago, I grew Lime Frost and although it was beautiful in bloom, it wasn't a very late bloomer in my garden. I remember it blooming around mid season. It was only one of two whites I grew, as I tended to grow the daylilies that were in color. Pat Stamile must have hybridized and registered this one while he lived in FL.
I love this one. I grow it in partial shade and its wonderful lime-tinged blooms glow. We get gall midge here in SW UK but although Lime Frost blooms mid-season here it has never been affects by this pest. I wouldn't be without it!
