The Hydrangea family is a very large one made up of five different branches: H. macrophylla (which includes H. macrophylla serrata), H. paniculata, H. arborescens, H. quercifolia, and H. anomala. These fabulous plants range in size from 18 inches to 60 feet (or more) in height. They can vary from a dense, bushy shrub, to a weeping tree, to a climbing vine. All Hydrangeas want a humus-rich soil, ample moisture, and relief from the midday sun. Beyond those demands, and an occasional cleanup pruning, they are easy, spectacular additions to any landscape.
