I had this daylily for several years, but no longer have it. I got it when I first became interested in toothy daylily flowers and it gave me many of those each year. They were much like the first picture, but perhaps the red was somewhat less intense because of the extreme heat and humidity our late-spring and summer brings. While the flowers didn't stand up to our weather any better that most other red daylily flowers, neither was it any worse.
Rosy Spiketail gave me a lot of toothy seedlings, although most were narrow form and often failed to have strong color intensity. However, every now and then I would get a couple of round form flowers with good coloration, generally when using Rosy Spiketail as the pollen parent. I am still growing a couple of the seedlings and evaluating them for possible registration.
For information, P E-12 was a seedling out of Bell's Depths of My Heart
