Pflege & Anbau
Prefers a sunny position with moist, free-draining soil. It is tolerant of neutral to slightly acid ground and benefits from mycorrhizal fungi in the root zone. Once established, it requires little intervention but may become very large; site accordingly.
Scientific profile
Pseudotsuga menziesii is a tall, evergreen tree belonging to the pine family (Pinaceae). Originating from western North America, it has been widely introduced elsewhere and is now established in the wild in Great Britain. Mature specimens can attain a height of up to 65 metres. The foliage consists of needle-shaped leaves that persist throughout the year, giving the crown a dense, dark green appearance. Flowering occurs in spring (April to May), after which woody cones develop. The tree forms arbuscular mycorrhizal associations, which aid nutrient uptake. It thrives in full sun and prefers moderately moist, neutral to slightly acid soils; it is adapted to cool, montane climates and shows low tolerance of severe disturbance.
