The Western thuja was first described by Carl Linnaeus in 1753, at the same time it received its biological name. The plant got its Latin name Thuja from the Greek language, where it means incense or sacrifice, which is associated with a pleasant smell that spread when burning aromatic wood species during ancient sacrifices. A slow-growing tree with a height of 12-20 meters, with a compact pyramidal or egg-shaped crown. The bark of young trees is smooth, red-brown, later gray-brown, separated by narrow longitudinal ribbons in old age. The needles are scaly, green, brown-green or brown in winter, small (0.2—0.4 cm), tightly pressed to the shoot, functions for 2-3 years and falls off together with small twigs (vetkopad). The upper side of the shoots is dark green and shiny, the lower side is matte, light. The cones are ovoid, small (7-12 mm), consisting of thin scales, contain two flattened, with two narrow straw-yellow wings of the seed. The wood is sound, reddish, relatively soft, very durable, without resin passages; has a pleasant aroma and is not subject to rot. The root system is compact. At home — calcefil. The main natural habitat of the western thuja is located in the southeastern part of Canada and the northern part of the USA. In particular, it extends westward from Anticosti Island in the Gulf of St. Lawrence to the southern part of James Bay, through the center of Ontario province to the southeastern part of Manitoba province; then southward through the center of Minnesota and Wisconsin, a narrow strip located around the southern tip of Lake Michigan; to the east - through the south of Michigan, the southern part New York State, central Vermont, New Hampshire and Maine. This species also grows in places in northwestern Ontario, western and central Manitoba, southeastern Minnesota, southern Wisconsin, northern and central Illinois, Ohio, southern New England, the Appalachian Mountains of western Pennsylvania, southern western North Carolina and eastern Tennessee. Thuja was imported to Europe in 1540.
