History/Lore

The name arborvitae, is a Latin form of the French, "l'arbre de vie," which means, "tree of life." Linnaeus, the Swedish botanist who assigned the Latin name to this species, picked up on other traits. The genus name, Thuja, is from a Greek word for perfume. Squeezing the evergreen leaves releases an aroma that is nothing less than nature's perfume.

America arborvitae was useful in early canoes and medicines and became the first North American tree to be introduced to Europe. The specific name, occidentalis, means "west," the direction from Sweden where this tree was discovered.
