( Thuja occidentalis)
Thuja occidentalis is an evergreen coniferous tree, in the cypress family Cupressaceae, which is widely cultivated for use as an ornamental plant. The endemic occurrence of this species is a north-eastern distribution in North America. It is thought to be the first tree of that region to be cultivated in Europe. An evergreen tree with fan-like branches and scaly leaves. Unlike the closely related species, Thuja plicata (Western Redcedar), it is only a small tree. Growing to a height of 10-20 m tall with a 0.4 m trunk diameter, exceptionally to 30 m tall and 1.6 m diameter, the tree is often stunted or prostrate. The bark is red-brown, furrowed and peels in narrow, longitudinal strips. The foliage forms in flat sprays with scale-like leaves 3-5 mm long. The cones are slender, yellow-green ripening brown, 10-15 mm long and 4-5 mm broad, with 6-8 overlapping scales. The branches may take root if the tree falls.[1] Eastern white cedars found to be growing on cliff faces in Southern Ontario are the oldest trees in Eastern North America and all of Canada growing to ages in excess of 1320 years old.[2] Native to the northeastern U.S. and southeastern Canada, from central Saskatchewan east to New Brunswick, and south to eastern Tennessee in the Appalachian Mountains.
