Korean Boxwood

Korean Boxwood (Buxus microphylla var. koreana)

Korean Boxwood is a cold-hardy evergreen shrub valued for its dense foliage, dependable structure, and strong performance in colder climates. Its naturally rounded to broad-mounded habit makes it especially useful in foundation beds, low hedges, border edging, and formal plantings where a finished look matters throughout the year. Because it stays relatively compact and tolerates winter conditions better than many other boxwoods, it is especially useful in northern landscapes. This is a strong choice for gardeners who want an easy-care evergreen that provides lasting form and a reliable focal point in every season.

Distinctive Features

This broadleaf evergreen shrub forms a dense, many-branched mound with small, glossy light to medium green leaves that create a fine evergreen texture in the landscape. It is especially valued for its cold hardiness and steady, slow growth, which make it a practical choice for gardens where winter reliability matters. Compared to some other boxwoods, it often has a looser, broader habit unless clipped, which gives it flexibility for both formal and more natural uses. The foliage may take on some bronze tones in winter, but the plant remains structurally useful and attractive year-round.

Growing Conditions

• Sun: Plant in full sun to part shade for the best density and overall performance.
• Soil: Provide moist, well-drained soil and avoid constantly wet or poorly drained sites.
• Water: Water regularly during establishment, then maintain moderate supplemental watering during dry periods.
• Zones: Hardy in USDA Zones 4 to 8.
• Mature Size: Commonly reaches about 2 to 3 feet tall and 3 to 4 feet wide, though older plants can become larger over time.
• Habit: Grows in a dense, rounded to broad-mounded form with a somewhat open character if left unpruned.

Ideal Uses

• Focal Point: Use it as a focal point in smaller foundation beds or formal borders where its dense evergreen form can anchor the planting year-round.
• Low Hedges: Plant it in rows to create neat low hedges with a clean, finished appearance.
• Border Edging: Add it along walks and garden edges where its compact habit helps define spaces clearly.
• Foundation Plantings: Use it around entryways, porches, and front beds where evergreen structure is needed without excessive height.
• Formal Gardens: Include it in structured layouts where evergreen mass and year-round texture help reinforce order.

Low Maintenance Care

• Watering: Keep soil evenly moist during establishment, then water during prolonged dry periods if needed.
• Pruning: Prune lightly in late spring or early summer if shaping is needed, especially if a tighter hedge or cleaner outline is desired.
• Mulching: Apply mulch around the root zone to help conserve soil moisture and moderate soil temperature.
• Placement: Shelter from harsh winter wind where possible to help reduce foliage stress and winter bronzing.
• Drainage: Ensure good drainage, especially in winter, to support long-term plant health.
