The smallest details count in landscape design, from storm water drainage to paving materials and seasonal plant color. It is not unusual, for example, for landscape architects to spend an entire day planning the placement of trash receptacles, said Michael D’Angelo, 27, a landscape architect at Copley Wolff Design Group in Boston.

D’Angelo’s experience ranges from green roof decks to college campuses. He is currently working on the penthouse terrace at The Clarendon, a 33-story luxury residential tower in the Back Bay. “I strive to make landscaping memorable,” he said, “by including a unique feature that draws people there, whether it’s a quiet corner to sit and read, or a beautiful garden terrace.”
