Boxwood is such an interesting plant because their shiny green leaves stay on the plant year-round even in areas that have snow and cold. There are different forms both spreading and upright. Boxwood in the colder climates may need some protection from the drying winter winds (on the west and north exposures) in some areas. Some of these newer selections are outstanding for areas into hardiness zones 5 and some even into zone 4. They are wildly popular especially into the colder climates to introduce some winter interest into the landscape. They make incredible sheared and formal hedges and the upright forms make perfect pyramidal specimens. Boxwood can also be used less formally and look great without shearing, but allowed to grow more naturally.
