Common Names


Trees of this genus are commonly called thujas or arborvitae (from the latin for "tree of life").  The two native American species, Thuja plicata and Thuja occidentalis are often called cedars, but because they are not true cedars (Cedrus) it has been recommended to call them redcedar or whitecedar, respectively.
