They're also incredibly easy by layering. Pick an outside stem, still attached, and bend it to the ground. Pull off a few leaves at the bottom. Create a shallow trench, about an inch or two deep, and bury those stripped nodes but leaving the tip of the stem above ground. In spring just sever the stem and dig it up. The buried nodes will have formed nice roots and you have a new plant. No muss, no fuss, nothing to babysit. Mother Nature does it for you.
