One landscape idea that's getting a lot of attention these days is outdoor rooms. More and more people are starting to enjoy the practical benefits of dividing their yards into discrete spaces.
There are many reasons to create outdoor rooms. You might want to entertain in one area and sit and contemplate in another. One area might be for the kids or even pets, while the other is for cooking.
You might have a water feature in one spot and a fire pit in another. Sometimes you want to see from room to room; other times, you want to build walls and completely separate the rooms.
You can use almost any plant material to create your walls, or you can use more conventional fencing materials such as stone or wood. You can even use containers or sculptures.
I like the idea of using very vertical plants such as Hicks Yew or Buxus Graham Blandy -- a type of boxwood -- for wall material. Sky Pencil Holly (Ilex crenata) work well, too, but can get winter damage in cold dry winters north and west of Boston.
The following chart, created by the Virginia Cooperative Extension Service, shows you some plants well suited for use as room dividers. Always check to make sure that a plant you're interested in can be used in your zone, and make sure you have the right light and soil conditions for the plant. Also think about what plants might differentiate your yard from everyone else's. Look for unique specimens that will not only be the walls of your outdoor room, but a wonderful conversation piece as well.
