Lawson's Cypress (Port Orford-Cedar)A Good Log Choice
Lawson's Cypress is one of the good choices for your house logs. It has a great reputation for stability and durability and should be a first choice for those homes being built in the south central states. It's reputation for decay resistance makes it more than a favorable species to consider in any of our humid climates.
A Reputation for Strength
Rated strongest among all types of Cypress, Lawson’s Cypress commonly known as Port Orford Cedar (POC) has earned a reputation for its strength and decay-resistance. This decay resistance is due to naturally occuring oils in the wood. POC has historically been the preferred wood for building boats and Japanese sacred temples. Today POC is ideal for flooring, interior woodwork, furniture, door construction and fence posts (its heartwood has an in- ground life of 20-25 years). POC has even been used to build the stadium seats at the world-famous Rose Bowl in Pasadena, California, park benches at Yosemite National Park and for building America's Cup yachts.
Rough Sawn Timbers
It's simple. Strength, durability and natural decay-resistance make POC the ideal wood for our Rough Sawn Timbers, where beauty and structural integrity are important in both indoor and outdoor uses.
Liven up An Interior
POC is a lightly colored wood, allowing it to accept stains nicely. And with a fine texture, straight grain, and pleasant sweet-spicy scent, it's an excellent choice for interior woodwork. Our paneling is available in clear or knotty styles, and in a variety of patterns of either rough or smooth surfaces. It can be installed vertically, horizontally, or diagonally, rough or smooth side out, providing plenty of design options.
Perfect for Exteriors
Our Appearance Plus decking made from POC is not only strong, it's safe for children. In addition to chemical-free decay deterrence, its texture remains smooth with no raised grain or slivering, and its durability makes it ideal for use in high- traffic outdoor sites. Using our 16 knife planer, we give this unique decking a gentle smoothness and soft luster.
Most importantly, our POC comes with the C&D Lumber commitment. Our strict written quality standards and specifications show our commitment to quality craftsmanship and customer service.
The Scientific Scoop
Chamaecyparis lawsoniana is a cypress in the genus Chamaecyparis, family Cupressaceae, known by the name Lawson's Cypress in the horticultural trade, or Port Orford-Cedar in its native range (although not a true cedar). C. lawsoniana is native to the southwest of Oregon and the far northwest of California in the United States, occurring from sea level up to 1,500 m (4,900 ft) altitude in the Klamath Mountains valleys, often along streams.
It is a large evergreen coniferous tree, maturing up to 200 feet tall or more, with trunks 4–6 feet in diameter, with feathery foliage in flat sprays, usually somewhat glaucous blue-green in color. The leaves are scale-like, 3–5 mm long, with narrow white markings on the underside, and produced on somewhat flattened shoots. The seed cones are globose, 7–14 mm diameter, with 6-10 scales, green at first, maturing brown in early fall, 6–8 months after pollination. The male cones are 3–4 mm long, dark red, turning brown after pollen release in early spring. The bark is reddish-brown, and fibrous to scaly in vertical strips.
It was first discovered (by Euro-Americans) near Port Orford in Oregon and introduced into cultivation in 1854, by collectors working for the Lawson & Son nursery in Edinburgh, Scotland, after whom it was named as Lawson's Cypress by the describing botanist Andrew Murray. The USDA officially calls it by the name Port Orford Cedar, as do most people in its native area, but as it is not a cedar, many botanists prefer to avoid the name, using Lawson's Cypress, or in very rare instances Port Orford Cypress, instead to stop confusion. The horticultural industry, in which the species is very important, mostly uses the name Lawson's Cypress.
The extinct Eocene species Chamaecyparis eureka, known from fossils found on Axel Heiberg Island in Canada, is noted to be very similar to Chamaecyparis pisifera and C. lawsoniana.
