'''Western Red Cedar''' ('''''Thuja plicata''''') is a species of ''[[Thuja]]'', an [[evergreen]] [[Pinophyta|coniferous]] [[tree]] in the cypress family [[Cupressaceae]].

The Western Red Cedar is a large tree, ranging between 40 to 150 feet (12 to 45 meters) tall and up to 22 feet (7 meters) in trunk diameter. Trees growing in the open will exhibit a crown that reaches the ground, whereas trees densely spaced together will only exhibit a crown at the top, where light can reach the leaves.<ref name="stewart 24"/>  Some individuals can live nearly a thousand years, if not more.

The foliage forms flat sprays with scale-like leaves in opposite pairs, with successive pairs at 90° to each other.

Western Red Cedar (Thuja plicata) is a species of Thuja, an evergreen coniferous tree in the cypress family Cupressaceae. In the American horticultural trade, it is also known as the Giant Arborvitae, Arborvitae being another name for its genus.

The Western Red Cedar is not actually a cedar (Cedrus), but belongs in the Cupressaceae family, along with cypresses. It is known by many names: Pacific red cedar, British Columbia cedar, canoe cedar, giant cedar, and red cedar.[1]

The Western Red Cedar is a large tree, ranging between 40 to 150 feet (12 to 45 meters) tall and up to 22 feet (7 meters) in trunk diameter. Trees growing in the open will exhibit a crown that reaches the ground, whereas trees densely spaced together will only exhibit a crown at the top, where light can reach the leaves.[2] Some individuals can live nearly a thousand years, if not more.

The foliage forms flat sprays with scale-like leaves in opposite pairs, with successive pairs at 90° to each other. The foliage sprays are green above, and green marked white with stomatal bands below. The cones are slender, 15–20 mm long and 4–5 mm broad, with 8-12 thin, overlapping scales.
