Oh gosh, this purple at the base of the fan has been around a LONG time. Some people call it "purple socks." I have seen it in some of the plants I grow of the Herringtons that show a lot of green in the throat. This traces back to an ancestor of some of Katisue Herrington's first " Oz" themed daylilies. One of the ancestors of ' Magic of Oz,' ( which does show the purple socks here, is (I've got to look this up, and will have to come back and insert it. It's an old Temple cultivar ) . OK, the plant I was looking for is ' Rainbow Spangles' an older Temple cultivar that I grew about 25-30 years ago. It had a very green throat, and also had the purple socks, and it is a ( grandparent?) of Magic of Oz, which was one of the first Herrington cultivars to get a lot of acclaim for its green throat. I believe Tim and I had a conversation years ago about their use of Rainbow Spangles. I've also heard Tim say many times, ( and if you've heard him speak. You've probably heard this too) that if you're looking to get green seedlings, cross green with green, it doesn't take a rocket scientist!
'Banana Pepper Spider' is another older Herrington cultivar that shows the purple socks. This spring, I dug my clump of ' Flying Monkeys' up, and sure enough, every fan was showing the purple socks. I think that when the Herringtons stumbled onto the very green throats they now breed for, that the plants with these "purple socks" seemed to show that genetic component.
Here's RAINBOW SPANGLES, a grandparent of Magic of Oz, which has a very green throat AND purple socks! I haven't traced this back further, but it might be interesting. Rainbow Spangles was registered in 1983, which makes it a 40 year old historic daylily.
