Atrovirens Western Red Cedar

Atrovirens Western Red Cedar (Thuja plicata 'Atrovirens')

Atrovirens Western Red Cedar is a strong, dark-green evergreen that quickly adds privacy and structure without looking bulky or messy. It grows into a tall, narrow pyramid that works as a living wall, a wind buffer, or a clean vertical accent in larger beds. Compared with many arborvitae, it tends to hold its rich color well and keeps a full, dense look when given enough light and moisture. If you want a dependable screen that still feels natural and classic, this tree delivers year-round coverage with a straightforward care routine.

Distinctive Features

This western red cedar selection is valued for glossy, deep green, scale-like foliage and a vigorous, pyramidal habit that can be maintained as a tall hedge. The foliage may look a bit less green in winter, but it remains an evergreen presence with strong texture and density. Mature plants develop an impressive, architectural silhouette, often reaching about 30 to 45 feet tall and roughly 10 to 15 feet wide when untrimmed. Small cones can appear, but the main appeal is the dark color, fast coverage, and reliable screening performance.

Growing Conditions

• Sun: Full sun to part shade, with the densest growth typically in brighter exposures.
• Soil: Moist, well-drained soil is best, and it adapts to many soil types if drainage is reasonable.
• Water: Provide regular water during establishment, then water during extended dry spells to keep foliage full.
• USDA Zones: 5 to 7.
• Site: Choose a spot with room for height and airflow, and avoid hot, reflected-heat locations that dry the root zone.

Ideal Uses

• Focal Point: Use one specimen to create a tall evergreen focal point with a clean pyramidal outline and dark, polished color.
• Screening: Plant in rows for a fast, dense privacy screen that can be left natural or maintained as a hedge.
• Windbreak: Establish along exposed edges to reduce wind and create calmer garden spaces behind it.
• Property Line: Define boundaries with a living wall that looks consistent through every season.
• Backdrop Planting: Set behind mixed borders to make flowers and lighter foliage colors stand out more.

Low Maintenance Care

• Pruning: Shear or lightly trim in late spring to early summer if shaping is needed, and avoid cutting back into bare, leafless wood.
• Mulching: Mulch the root zone to conserve moisture and moderate soil temperatures, keeping mulch off the trunk.
• Watering: Deeply water during drought, especially for hedges where roots compete closely.
• Fertilizing: Feed in spring only if growth is weak, using a slow-release evergreen fertilizer according to label directions.
• Winter Care: In snowy areas, gently remove heavy, wet snow to reduce branch splay and preserve form.
