Carnations and Dianthus are very closely related and they do prefer cooler growing conditions. They probably could be crossed with each other. I considered the Dianthus species as a candidate for hobby breeding, but couldn't find enough genetic material with yellow and orange colorations. With the right timing and variety selection, you should be able to grow Dianthus. They have some striking color patterns and plant habits. And their foliage seems to be resistant to problems.
Grin. I strongly suspect that you couldn't get a yellow/orange/light purple color combination, like in this Zig Zag zinnia, in a carnation or dianthus.
