A tree isolated within a moat of shrubs, rocks, pavers, or flowers adds majesty to an otherwise nondescript patch of land. Positioning a single tree or a cluster of dainty white birches in the middle of a circular drive or other island will give it a dramatic centerpiece. You can also landscape to draw attention to an impressive tree. The shallow root system and shade thrown by this Norway maple in Bergen County, New Jersey prevented grass from growing beneath it. The homeowners made a virtue of the problem by setting the tree off with a gravel surround and footpath.
