Blue Nootka Cypress

Blue Nootka Cypress (Chamaecyparis nootkatensis 'Glauca')

Blue Nootka Cypress is a graceful evergreen conifer valued for its blue-green foliage, broad upright habit, and strong year-round landscape presence. Its sweeping branches and glaucous color bring a refined, natural look to specimen plantings, evergreen screens, large hedges, conifer gardens, and spacious mixed borders. This selection has more color contrast than the straight species while maintaining the durable structure and character of Nootka Cypress. With full sun, moist well-drained soil, and protection from severe drought, Blue Nootka Cypress brings dependable evergreen height, texture, and cool-toned color to larger landscapes.

Distinctive Features

Blue Nootka Cypress forms an upright evergreen tree with broad, sweeping branches and finely textured blue-green to glaucous foliage. Young plants often have ascending branches, while older specimens develop a broader pyramidal outline with more horizontal branching. Small rounded cones may appear among the foliage, adding subtle seasonal detail without becoming the main ornamental feature. This cultivar is grown primarily for its cool foliage color, strong branching, evergreen structure, and useful performance in moist and coastal-influenced conditions.

Growing Conditions

• Sun: Grows best in full sun, with some light partial shade tolerated in suitable climates.
• Soil: Prefers moist, well-drained soil and performs best where roots are not exposed to severe drought, compaction, or prolonged dryness.
• Water: Water regularly during establishment, then provide supplemental water during extended dry periods to maintain healthy foliage and steady growth.
• USDA Zones: Hardy in USDA Zones 5 to 8, with best performance in cooler, moist climates and protected sites.
• Mature Size: Typically reaches about 25 to 40 feet tall and 10 to 20 feet wide in cultivation, with size depending on climate, age, and site conditions.
• Habit: Forms a broad upright to pyramidal evergreen conifer with sweeping branches and fine blue-green foliage.

Ideal Uses

• Focal Point: Use as a cool-toned evergreen focal point in spacious front yards, conifer gardens, estate landscapes, or open mixed borders where its blue foliage and branching can stand out.
• Specimen Planting: Feature as a standalone conifer where its glaucous foliage, pyramidal form, and sweeping branch structure can be appreciated through every season.
• Screening: Plant in loose groups or informal rows where a tall evergreen screen is desired and there is enough room for long-term growth.
• Large Hedge: Use as a broad evergreen hedge in spacious landscapes where pruning can encourage dense new growth and maintain size.
• Coastal Landscape: Plant in suitable coastal or moist-climate settings where its tolerance for cool, moist conditions can support strong performance.

Low Maintenance Care

• Watering: Water deeply during the first few seasons to establish roots, then water during prolonged dry spells as needed.
• Mulching: Apply mulch around the root zone to conserve moisture, moderate soil temperature, and reduce weed competition while keeping mulch away from the trunk.
• Pruning: Prune lightly in spring as needed to shape, remove dead growth, or encourage a denser hedge form, avoiding hard cuts into old bare wood.
• Spacing: Provide enough room for its mature height and spread, especially when using it as a specimen or informal screen.
• Fertilizing: Fertilize only when needed in spring based on soil conditions, using a moderate approach that avoids excessive soft growth.
• Site Protection: Avoid hot, dry, exposed sites and provide protection from severe drying wind where possible.
