Western Red Cedar is the largest of all cedars, slow-growing and long-lived. It is completely non-resinous and is one of America's most decay-resistant species, making it a preferred species for outdoor and exterior uses. The narrow sapwood is almost pure white. The heartwood varies from a dark reddish-brown to a light yellow. It has a strong aromatic or spicy odor. It is one of the lightest in weight of the commercially important softwoods and suffers little when exposed to the weather without protection.
