You are welcome.
I love coneflowers. They are rated to zone 9. I figured since I was in Cape Coral, Zone 10, that some how my love for them would safely bring them through. No way!!
They sautéed like onions.
You cant underestimate the intensity of Florida sun. Where you are the sun is almost directly overhead! And when it's near 90, for six months on end, it is hard to grow some of these things!
