Thanks for the heads-up on Sky series. The article is spot on.
I agree about Summer Sky. and will add ,when its starting to pass bloom the petals are blotchy and rusty.I lso agree about not enough color gradiation ,too subtle.
I have TiKi torch and its increasing well but the other orange Sundown is not taking hold and has distorted blooms also. It has one more year here and then OUT.
I didnt think about phlox with DL's I will need to check that part of my garden to see how they might be wedged in.
Thank you everyone who took time to send advise and photos.
