During the Colonial Period of America, American arborvitae, Thuja occidentalis, was one of the first native species to become popular for home gardening. It is native as far south as the Great Smoky Mountains, and as far east as Minnesota. Wild trees can be fifty feet tall, with trunks as wide as three feet. They might grow larger to compete with other trees.

Of course, the oldest cultivated varieties, as well as relatively modern cultivars, are much more compact. Many modern cultivars are hybrids. Some are different species. They are densely evergreen shrubbery that work well as hedging. Their distinctly ruddy or grayish brown bark is barely visible. Their bloom is unimpressive. Foliage is their primary asset.

It is quite an asset. Although arborvitae is conducive to shearing, its billowy foliar texture is too appealing to compromise by frequent shearing. Scale leaves are barely more than an eighth of an inch long, like those of junipers, but are more pliable on soft and flattened foliar sprays. Such sprays are delightful coniferous evergreens for wreaths and garlands.
