Title: Flat leaf cedar, Thuja occidentalis (arborvitae)
Answered by: Jimmy Mills

QUESTION:

Hello, I am looking for the scientific name for what is commonly called flat leaf cedar. It has defined platelets, wonderful cedar smell, older trees have shaggy bark, in winter some of its sprays turn brown and drop, has small cones in clusters, sometimes used as tea, used by Native Americans, can grow quite tall, branches droop... Thank you very much.

ANSWER:

Thuja occidentalis (arborvitae) is the scientific name of the flat leaf cedar, and USDA Plants will show you an image. Interestingly, it is probably the first North American tree introduced into Europe, it was discovered by French explorers and grown in Paris about 1536. The year before, tea prepared from the foliage and bark, now known to be high in vitamin C, saved the crew of Jacques Cartier from scurvy. It was named arborvitae, Latin for "tree-of-life," in 1558.
