Summary
A tidy green mound that keeps its shape with very little help.
Green Mound is a hybrid boxwood bred for colder gardens, combining the fine texture of English boxwood with the toughness of Korean boxwood. The result is a dense, naturally rounded shrub about three feet tall and wide with small, glossy green leaves.
That built-in rounded form is what makes it useful. Planted alone it reads as a neat globe, and planted in a row it knits together into a low, even hedge for edging beds, lining walks, or framing a formal garden. It needs far less shearing than boxwoods that grow loose and open.
The foliage holds its green through winter better than many boxwoods, so the structure it gives a garden stays in place after perennials die back and deciduous shrubs go bare.
Care
Green Mound Boxwood Care
Plant in full sun to partial shade. In colder zones, a site sheltered from strong winter wind and late-day winter sun helps prevent foliage bronzing.
Boxwood needs well-drained soil and will decline in ground that stays wet. It tolerates a range of soil types, including clay that drains reasonably well, and prefers a pH near neutral.
Water deeply once or twice a week through the first growing season. Boxwood roots are shallow, so a one-to-two-inch layer of mulch helps hold moisture; keep mulch a few inches away from the stems. Established plants handle short dry spells, and a deep watering before the ground freezes helps prevent winter burn.
Feed lightly in early spring with a slow release fertilizer. Boxwood does not need heavy feeding.
Shape lightly in late spring or early summer after the first flush of growth hardens. Because it grows naturally rounded, most years a single light trim is enough. Good air circulation and avoiding overhead watering help keep foliage healthy. Where boxwood blight is present in your area, space plants so air can move between them and clean pruning tools between plants.
Growing in Containers
Boxwood grows well in containers and is a classic choice for flanking a door. Use a pot with drainage holes and a quality potting mix, water whenever the top inch of mix feels dry, and feed lightly in spring, since frequent watering washes nutrients out. Roots in containers experience greater cold exposure than roots in the ground. Plants hardy in the ground may require winter protection when grown in containers in colder zones.

Additional Information
What are some common names for this plant?
It is most often called boxwood, and is sometimes simply called box.
Can I use it for a low hedge?
Yes. Its rounded shape and steady size make it one of the easier boxwoods for a low hedge. Space plants two to three feet apart and they will grow together into a continuous row. Browse more Evergreen Plants.
Will deer eat it?
Deer and rabbits rarely browse boxwood, which makes it one of the most dependable evergreen shrubs for gardens with regular deer pressure. See our Deer-Resistant Shrubs and Evergreens for more options.
Does it turn bronze in winter?
It holds its green better than many boxwoods, but any boxwood can bronze slightly in exposed, windy sites or under strong winter sun. A sheltered location and a deep watering in late fall help. See our Shrubs & Bushes for more choices.
