Hedges add beauty to the landscape and so much more. They can provide structure and shade to your landscape, create privacy and muffle sound. A hedgerow, or living fence, is so much more beautiful than a wooden or metal fence. Some shrubs for hedges, like purple leaf plum and dwarf burning bush, provide months of colorful foliage. Hydrangeas add pops of color when their flowers burst into bloom. When selecting shrubs for hedges to buy online, make sure they are suitable for your grow zone. Next, check their light requirements (full sun, partial shade or full shade). Other considerations are soil requirements, mature height and spread, foliage color and bloom time (if applicable).
