OK, so what is this shrub that is everywhere?
OK, probably everyone but me knows the name of this shrub, but it's everywhere here in central NY, it's got an arching habit, it can get pretty big (I guess 6 feet or more), it grows in shade, it is covered with creamy-white astilbe-like fluffy flowers in Aug-Sept (at least), it's got big heart shaped to oval leaves, not serrated, they reming me of red-twig dogwood leaves. The long arched stems are dark. What am I???
