Range of T. plicata in the Pacific Northwest

Thuja plicata, commonly called western redcedar[2] or Pacific redcedar,[3] giant arborvitae or western arborvitae,[3] giant cedar,[3] or shinglewood,[3] is a species of Thuja, an evergreen coniferous tree in the cypress family Cupressaceae native to western North America. It is not a true cedar of the genus Cedrus.


Thuja plicata is among the most widespread trees in the Pacific Northwest. It is associated with Douglas-fir and western hemlock in most places where it grows. It is found at the elevation range of sea level to a maximum of 2,290 m (7,510 ft) above sea level at Crater Lake in Oregon.[4] In addition to growing in lush forests and mountainsides, western redcedar is also a riparian tree, growing in many forested swamps and streambanks in its range.[5] The tree is shade-tolerant and able to reproduce under dense shade.[6]

It has been introduced to other temperate zones, including western Europe, Australia (at least as far north as Sydney), New Zealand,[7][8] the eastern United States (at least as far north as Central New York),[citation needed] and higher elevations of Hawaii.[9]

The species is naturalized in Britain.[10]
