Eastern White Cedar (Thuja occidentalis) is an iconic native Quebec conifer valued for its dense evergreen foliage, elegant form, and exceptional hardiness. Its flattened emerald-green sprays retain their colour throughout the year and provide structure in gardens, hedges, and natural landscapes. This long-lived tree develops a graceful silhouette and offers outstanding winter interest with its persistent foliage, even through the cold conditions of northern regions.
Eastern White Cedar (Thuja occidentalis) thrives in rich, moist to wet, well-drained soils. It prefers sun to partial shade and adapts well to Quebec growing conditions. Seeds require soaking and cold stratification before sowing to improve germination. Once established, this tree requires little maintenance and tolerates harsh winters. Adding organic matter in spring supports healthy and balanced growth.
Eastern White Cedar (Thuja occidentalis) is ideal for windbreaks, privacy screens, reforestation projects, and ecological landscapes. Its dense foliage provides valuable shelter for birds and small wildlife throughout the year. Combined with white spruce, American mountain ash, and Labrador tea, it helps create diverse forest-inspired plantings. Its presence strengthens biodiversity while adding lasting ornamental value.

Growing method
Sow seeds in autumn or spring after soaking followed by cold stratification to improve germination. Plant the seeds about 3 mm (0.1 in) deep in a light, evenly moist growing medium. Temperatures between 18 and 20°C (64 to 68°F) typically produce germination within 30 to 45 days. Young seedlings appreciate bright light while being protected from extreme conditions. Transplant them into rich, cool, well-drained soil in full sun or partial shade. This native conifer is exceptionally well adapted to Canadian climates and can thrive for many decades.
