North Star Boxwood

North Star Boxwood (Buxus sempervirens 'Katerberg')

North Star Boxwood is a compact evergreen shrub that brings year-round structure, dependable color, and a naturally tidy look to the landscape. Its dense, rounded habit makes it especially useful in foundation beds, low hedges, border edging, and containers where a polished appearance matters without needing a large shrub. Because it stays relatively small and keeps a strong green color through winter, it fits comfortably into tighter spaces while still providing lasting evergreen presence. This is a strong choice for gardeners who want an easy-care boxwood that offers refined form and a reliable focal point in every season.

Distinctive Features

This broadleaf evergreen shrub forms a dense, compact, globe-like mound of small green leaves that remain attractive through the year. It is especially valued for its naturally tight habit and its ability to retain a healthy green color through winter when that evergreen presence matters most. Compared to larger or looser boxwoods, North Star offers a more controlled, low-maintenance form that works especially well in edging and low hedge applications. It has also shown useful resistance to boxwood blight, which adds practical value in modern landscapes.

Growing Conditions

• Sun: Plant in full sun to part shade or shade for the best overall performance and placement flexibility.
• Soil: Provide well-drained soil and avoid constantly wet or poorly drained sites, with slightly acidic to slightly alkaline soil preferred.
• Water: Water regularly during establishment, then maintain average supplemental watering during dry periods.
• Zones: Hardy in USDA Zones 5 to 9.
• Mature Size: Reaches about 2 to 2.5 feet tall and 2 to 2.5 feet wide.
• Habit: Grows in a very dense, compact, rounded globe form.

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.
• Containers: Grow it in large containers where its tidy shape and evergreen foliage can provide long-lasting structure.

Low Maintenance Care

• Watering: Keep soil evenly moist during establishment, then water during prolonged dry periods if needed.
• Pruning: Prune lightly in late spring if shaping is needed, after new growth has emerged but before it hardens off.
• Feeding: Apply a granular fertilizer for woody plants in early spring only if needed, because heavy feeding is usually unnecessary.
• Mulching: Apply a 2 to 3 inch layer of mulch around the root zone to conserve moisture and help reduce winter stress.
• Winter Care: Water during dry autumn periods before the ground freezes, since winter drought stress can be a major cause of foliage damage.
