Growing a hedge along a walkway or property line is a great alternative to a wood or metal fence. Hedges add beauty to the landscape, provide structure, muffle sound and create privacy. Many types of shrubs can be used for hedging. Because they retain their foliage year round, evergreens such as arborvitae and juniper, are popular. Deciduous shrubs, such as burning bush, can provide lush foliage that changes color in the fall. Flowering shrubs can also be used for hedging. When growing shrubs for hedge rows, an important consideration is the variety's mature height and spread. Other factors to consider are hardiness zone, sunlight requirements and maintenance needs.
