Excelsa Western Red Cedar

Excelsa Western Red Cedar (Thuja plicata 'Excelsa')

Excelsa Western Red Cedar is a strong evergreen choice when you want privacy that still looks natural and calm, not stiff or overdone. It builds a tall, dense screen with rich green color, helping you block views, soften property lines, and create a more sheltered backyard. The upright pyramidal shape gives you structure all year, and it can be left to grow naturally or lightly maintained for a cleaner edge. If you want a dependable, long-lived screen with a classic look, this is an easy plant to design around.

Distinctive Features

This cultivar is a denser, more compact form of western red cedar with glossy, scale-like evergreen foliage arranged in layered sprays. Its habit is upright and pyramidal, creating a full, green wall effect when planted in rows, while still reading as a graceful conifer when used as a specimen. It typically matures around 30 to 40 feet tall and about 12 to 15 feet wide, offering substantial screening without the extreme size of the species. Small cones may appear, but the main value is the deep green color, dense branching, and reliable coverage.

Growing Conditions

• Sun: Full sun to part shade, with the best density usually in brighter light.
• Soil: Moist, well-drained soil is ideal, and it can tolerate damp soils if drainage is not stagnant.
• Water: Water regularly during establishment, then provide deep watering during extended dry periods for best fullness.
• USDA Zones: 5 to 7.
• Spacing: Space plants to match the privacy goal, giving enough room for airflow and mature width.

Ideal Uses

• Focal Point: Use one as a tall evergreen focal point to anchor a large bed with a clean pyramidal silhouette and rich green texture.
• Screening: Plant in rows to create a dense privacy screen that can be left natural or lightly shaped.
• Hedge: Maintain as a tall hedge for a more uniform look along property lines and fence lines.
• Windbreak: Use as a living wind buffer to make patios and gardens feel calmer and more protected.
• Backdrop Planting: Place behind mixed borders to highlight flowers and lighter foliage with a deep green evergreen background.

Low Maintenance Care

• Pruning: Prune lightly in late spring to early summer to refine shape, avoiding severe cuts into bare, leafless wood.
• Mulching: Mulch the root zone to conserve moisture and moderate soil temperatures, keeping mulch a few inches off the trunk.
• Watering: Keep soil evenly moist during the first couple of seasons, then water deeply 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: In snow areas, gently remove heavy, wet snow to reduce branch splay and protect the natural form.

Why Choose Excelsa Western Red Cedar?

• Moisture Tolerance: Handles consistently moist sites better than many common screening evergreens when drainage is reasonable.
• Deer Tolerance: Often less preferred than many soft evergreens, but protection may still be needed where deer pressure is high.
