Designer Brenda Gousha planted two 6-foot-long overlapping hedges of Carolina laurel cherries (Prunus caroliniana) and ran a 2-foot-wide path between them.
Gousha says walls of foliage also make the perfect outdoor room. "When my husband and I sit out here, we're just a few feet from the street. But we have complete privacy."
