If If We this one you can prune off as much as you like. Mine hasn't finished flowering yet so I have just removed the stems that are finished. I'll do the rest when they finish flowering. When the leaves drop, I will cut it right back. You can shape it now and remove anything that is in the way or strangling another plant and later when the leaves drop cut back to a size that is smaller than you want it to be eventually. You can do this any time before the leaves return. You won't damage the plant by pruning it.
