Tall, imposing conifer, broadly conical when young but becoming more columnar as it matures, with down-swept lower branches. Young trees have smooth grey bark, later becoming thick, deeply ridged and reddish-brown. Dark green linear leaves about 3cm. long and roughly arranged in two ranks along the shoots. They are fragrant when crushed.
Cones are up to 10cm long and have conspicuous long pointed bracts.
Most moist, well drained soils but not very chalky ones. May attain even greater height in ideal conditions. Young trees reach about 8 metres in 10 years.
Stately specimen tree for park and large spaces. Important for timber.
Discovered by Archibald Menzies around 1792 and introduced to Europe by David Douglas in 1827.
