Cupressaceae -- Cypress family
William F. Johnston
Northern white-cedar (Thuja occidentalis) is also called eastern white-cedar, arborvitae, and swamp-cedar. The name arborvitae or "tree of life" dates from the 16th century when the French explorer Cartier learned from the Indians how to use the tree's foliage to treat scurvy. A record tree in Michigan measures 175 cm (69 in) in d.b.h. and 34 m (113 ft) in height. The rot- and termite-resistant wood is used principally for products in contact with water and soil. The tree provides valuable shelter and browse in winter deeryards, and it is a widely planted ornamental.
