'''Western Red Cedar''' ('''''Thuja plicata''''') is a species of ''[[Thuja]]'', an [[evergreen]] [[Pinophyta|coniferous]] [[tree]] in the cypress family [[Cupressaceae]]. In the American [[Horticulture|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 [[cypress]]es. It is known by many names: Pacific red cedar, British Columbia cedar, canoe cedar, giant cedar, and red cedar.<ref name="stewart 22">Stewart (1984), p. 22</ref> 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. The foliage sprays are green above, and green marked white with [[stomata]]l bands below. The [[conifer cone|cones]] are slender, 15–20 mm long and 4–5 mm broad, with 8-12 thin, overlapping scales. {{Inc| ''[[Thuja]] plicata'', Don (T. gigantea, Nutt. T. Menziesii, Douglas. T.
