This coniferous evergreen is more appealing as seasonal foliar decor than it is practical. Western red cedar, Thuja plicata, is the most common component of Christmas garlands. Also, it is very popular for wreaths of mixed evergreens. It is the same genus as common arborvitaes. However, this particular species is notably rare among local home gardens.

Western red cedar is native to the Pacific Northwest. Its range extends south to the north coast of California, and east to western Montana. It therefore does not adapt efficiently to the arid warmth of local chaparral climates. Even with generous irrigation, its foliage can be vulnerable to desiccation. The healthiest specimens here are within coastal climates.

Like some other trees within its native range, western red cedar typically grows very big. It can easily reach a hundred and fifty feet tall, and can grow taller than two hundred feet. Although it does not grow as fast as redwood, it eventually needs about as much space. Western red cedar, here, is appropriate only for large landscapes within coastal climates. It is too obtrusive for compact home gardens.
