Thuja (pronounced Thuya) is a genus of coniferous trees in the Cupressaceae (cypress family). There are five species in the genus, two native to North America and three from Eastern Asia. They are commonly known as arborvitae (from Latin for tree of life), and some are colloquially known as cedars.The thuja can grow 3-5 feet (1-1.5meters) per year and can obtain heights of nearly 50 feet (15 meters). Amongst its many uses is the ability to create a natural privacy fence in a very short time.The leaves of Thuja are evergreen and scale-like, except young seedlings, where they are needle-like. The scales are arranged in four rows along the twigs. Thuja species are used as food plants by the larvae of some Lepidoptera species including Autumnal Moth, The Engrailed and Juniper Pug.
