Hi, Tomislav,
Your C. 'Palette' is fully hardy so unless you live in an area with very to extremely cold winters, you don't need to do anything. If your winters get to -25C or below, then you would want to protect it from cold, drying winds and freezing with horiticultural fleece/hessian or the like.
