Blue Atlas Cedar
Cedrus atlantica 'Glauca'Blue Atlas Cedar is a large evergreen conifer prized for its distinctive blue to blue-gray needles and striking architectural form. The foliage is arranged in dense clusters along spreading branches, creating a cool-toned texture that remains attractive throughout the year. Young trees typically develop an open pyramidal shape, while mature specimens develop broad, horizontal branches and a more irregular, picturesque silhouette. Upright, barrel-shaped cones may develop on mature trees, adding additional ornamental interest.
Reaching approximately 40′ – 60′ tall and 30′ – 40′ wide, Blue Atlas Cedar requires substantial room to develop its mature form. It is best used as a specimen tree where its unusual blue foliage and broad branching structure can serve as a focal point. The evergreen canopy also provides year-round structure and winter interest in spacious landscapes. Its dramatic appearance makes it particularly effective in large lawns, estates, and expansive garden settings where the tree can grow without crowding nearby structures or plants.
Blue Atlas Cedar grows best in full sun and moist, well-drained soil. It adapts to chalk, clay, loam, and sandy soils and tolerates acid, alkaline, and neutral pH. Established trees have good drought tolerance, but consistent moisture supports growth, particularly while young. The tree develops a deep taproot and can be difficult to transplant, so it should be planted carefully in a permanent location. Protection from strong winds is recommended, and adequate space should be provided for its mature size.
Care Instructions:
Planting: Plant in full sun in a permanent location with ample room for mature growth. Water thoroughly after planting.
Soil: Adaptable to chalk, clay, loam, and sand; prefers moist, well-drained soil.
Watering: Water regularly during establishment; established trees tolerate drought but benefit from moisture during prolonged dry periods.
Fertilizing: Apply a balanced fertilizer in spring according to product directions.
Pruning: Avoid unnecessary pruning. Allow the natural pyramid shape to broaden, spreading form to develop.
Spacing: Provide at least 30′ – 40′ of open space for the mature canopy.
Maintenance: Protect young trees from strong winds and avoid relocating established trees.
With its steel-blue evergreen needles, dramatic branching structure, and imposing mature size, Blue Atlas Cedar is a distinctive specimen tree for spacious landscapes. Its unusual foliage provides year-round color and winter interest, while its architectural form creates a strong focal point. Its tolerance of drought once established and adaptability to several soil types add to its landscape value, but its ultimate size and deep taproot make careful site selection essential. Please note that Blue Atlas Cedar is best suited to landscapes with sufficient room for its mature dimensions.
