We find that the most beautiful and intriguing gardens make use of hedges to create a bit of mystery, to encourage flow throughout the garden and to make unique garden rooms. Hedges can also create privacy, define spaces, add linear structure, or be used as a living fence. Hedges are shrubs that are planted so that they grow together to make a fence or border. They can be short, 1-2' tall, and used to define spaces and create paths. Medium-growing hedges, 3-5' tall, are nice to create garden rooms, which encourage folks to wander throughout the garden, turning corners to see what delight is around the next bend. They also provide a nice backdrop for perennials and accent shrubs. Taller hedges are generally used for privacy screens.
