Of those, I only grow Rozanne, but it is doing very well in 3/4 sun here in Atlanta. I suspect it could go full sun easily where you are.

If you haven't heard from anyone else, I'm growing Karmina in Cincinnati. They get maybe 6-7 hours of sun, I've got osage orange trees on either side of my 80' wide lot so it's not true full sun. This is their second year. I spent a lot of time last summer improving the clay soil with peat, pine fines, and composted manure, and they have exploded. I put in 4" pot-size plants last July, and they're easily 18" across now! The foliage is about 12" high, the flower stems are maybe 16-18" high and covered with blooms. I'm so happy with them I've become a geranium proselytizer! They're in front of Shasta Daisies and the combination looks gorgeous all summer. Highly recommended!
