 So they keep their foliage right through winter. They're perennial, but they don't die back to the ground and then come back fresh from the ground. They actually stay up and just up there, just right up there in the sun, more sun, the more beautiful they get. I'd say they need at least four to five hours of sun, personal experience or more, but euphorbias, rainbow ascot, gopher spurge, and then look at the merlot.
