Hedges

 

In colonial times, and in many gardens today, hedges were used to outline a garden. These were used often as natural fences as well as used for their beauty. In Virginia, boxwoods were a very popular shrub used. A popular use, if one had the money, was to cultivate a maze or labyrinth. 

Well-tended shrubbery presented a place for private conversations and good hiding places for children's games. One could relax in the shade, or follow a trail to the rest of the garden. 

However, because plants like these tended to grow copiously, it was important to keep them in check. Every place a person went, these plants could be seen and recognized." -- National Park Service
