Description
A nonspecific term used for wood from several aromatic evergreen trees. The best known cedar is the Cedar of Lebanon (Cedrus libani) which is native to Asia Minor. Cedars are characterized by having an strong smelling volatile oil whose odor persists after the wood is cut and dried. The wood has a fine grain, is a red and yellow in color and takes a beautiful polish. Cedar is durable and very resistant to insects and rotting.
