Port Orford Cedar

Scientific Name: Chamaecyparis lawsoniana

exterior paneling detailOther common names: Hinoki, pacific white cypress, oregon cypress, pacific white cedar. Originally grown only in southern Oregon and Northern California, Port Orford is a truly unique cedar species. Like all cedars, it is a member of the cypress family. It is a particularly hard and strong cedar, with the same natural durability as other types of cedar when it comes to weather, rot and insects.

Port Orford Cedar has earned a reputation for strength and decay-resistance. Historically, as the strongest of all the cedar products it has been the preferred wood for japanese architecture, building boats, railroad ties and fence posts (its heartwood has an in-ground life of 20-25 years by the Oregon State D.O.T.). Strength, durability and natural decay-resistance make POC the ideal wood for timber structures renown for its beauty and structural integrity, useful for both indoor and outdoor uses. POC is a light colored wood, allowing it to stain uniformly. It´s fine texture, straight grain, and pleasant, sweet-spicy scent, makes it an excellent choice for woodwork. Decking made from POC is not only strong, it´s safe for children. Its texture remains smooth with no raised grain or splintering, and it´s durability makes it ideal for use in high-traffic outdoor sites. Read more below...

Port-Orford-cedar (POC)

is one of the white-cedars in a group of “false-cypresses,” numbering three native species in the U.S. and four additional species in Japan and Taiwan. The Port-Orford-Cedar was first discovered in its small natural range along the California/Oregon coast in 1851. The total range was only about 200 miles long north and south and about 50 miles deep, shared by both states, about 70 percent in Oregon. Port-Orford-cedar, also known as Port-Orford white-cedar, Oregon-cedar and Lawson cypress prefers a mild climate with plenty of rain (40-90 inches annually)! High humidity and misting from the Pacific Ocean are also factors in the healthy growth of this tree in its natural areas. The range has been extended by planting the original and its variations around much of the northern half of the world and in New Zealand. These large attractive and very shade-tolerant trees grow to 125’ to 180’ in 500 years, with diameters of 3 1/2" to 6". A record tree, 219’ tall with a diameter of 12’, standing in Siskiyou, Oregon may be 700 years old. The wood of Port-Orford-cedar is clear with a straight, but somewhat uneven, medium grain. The wood is yellow-white in color, sometimes with tinges of red and has a bitter ginger taste/smell. Sapwood is hardly distinguishable from heartwood. Relatively lightweight and with good strength, this wood has a specific gravity of 0.40 and weighs about 27 pounds per cubic foot at 8% moisture content, about the same as Eastern Hemlock and a little heavier than Eastern White Pine.

Legendary Durability and Long life:

Historically preferred for marine applications such as docks and fine boat building. Rated to 20-25 years in ground post life. Exceptional Strength:Port Orford Cedar is exceptionally strong for a softwood. In tests for crushing strength, bending, shearing strength and side hardness, Port Orford outperformed all other Cedars and Redwood. Specifically 45% stronger than Redwood or Western Red Cedar in impact bending and 30% stronger in crushing strength. This wood is in great demand in China and Japan for coffins, and for temple construction because of its close relationship to Hinoki cypress (Chamaecyparis obtusa) which is thought to have a spiritual nature.
