The western white pine was named by David Douglas in 1831 while on a journey exploring the west coast of North America. It is found in southern British Columbia and Alberta down to northern California and Utah.
These very large trees reach heights of 165 feet (50 metres) and live about 400 years.
Its bluish green needles in bundles of five vary in size from 2 to 4 inches (5 to 10 centimetres).
The western white pine thrives on a variety of soils, but grows best in moist valleys and on gentle slopes.
It rarely occurs in pure stands, and is usually mixed with other species.
It is commonly called a soft pine because its wood is soft. Its creamy-white and moderately decay-resistant wood is used for items such as window sashes and frames, patterns, mouldings, doors, trim wooden matches and siding. Also, because of its softness, it is valuable wood for carving sculptures.
Needles, bluish green, in bundles of five.
Fruits, cones, 10 to 30 cm long.
