Northern Spire Western Red Cedar

Northern Spire Western Red Cedar (Thuja plicata 'Northern Spire')

Northern Spire Western Red Cedar is a space-smart evergreen that delivers privacy and structure without the wide footprint of many screening plants. Its tall, narrow form makes it easy to create a living wall along property lines, fences, and tight side yards while keeping beds and walkways open. The deep green foliage stays attractive year-round, giving the landscape a calm, finished look even in winter. If you want fast coverage with a clean, vertical profile, this is a dependable choice for long runs of screening.

Distinctive Features

This western red cedar cultivar grows with a tight, columnar to narrow pyramidal habit and dense, glossy sprays of scale-like foliage. The overall look is refined and uniform, with strong vertical lines that read well in both formal and natural designs. It is valued for filling in quickly once established, forming a thick screen that still feels fresh and green through the seasons. Small cones may appear, but the main appeal is the narrow silhouette, rich evergreen color, and reliable density.

Growing Conditions

• Sun: Full sun to part shade, with the densest growth usually in brighter light.
• Soil: Adaptable, best in moist, well-drained soil, and it can handle heavier soils if drainage is not stagnant.
• Water: Water regularly during establishment, then water deeply during extended dry periods for best fullness.
• USDA Zones: 4 to 8.
• Mature Size: Typically about 15 to 20 feet tall and about 4 to 5 feet wide.

Ideal Uses

• Focal Point: Use a single plant as a tall evergreen focal point to add clean vertical structure in a narrow bed.
• Screening: Plant in rows for a space-saving privacy screen that builds height and density quickly.
• Hedge: Maintain as a narrow hedge for a more uniform look along fences and property edges.
• Windbreak: Use to reduce wind and create calmer garden and patio spaces behind it.
• Backdrop Planting: Place behind mixed borders to make flowers and lighter foliage colors stand out more.

Low Maintenance Care

• Pruning: Prune lightly in late spring to early summer if shaping is needed, and avoid severe cuts into bare, leafless wood.
• Mulching: Mulch the root zone to conserve moisture and moderate temperatures, keeping mulch a few inches off the trunk.
• Watering: Keep moisture steady for the first couple of seasons, then water during drought to prevent thinning.
• Fertilizing: Feed in spring only if growth is weak, using a slow-release evergreen fertilizer according to label directions.
• Winter Care: Brush off heavy, wet snow to reduce branch splay and help maintain the narrow form.
