Lawson's cypress

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.

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 mountain valleys, often along streams.

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. More
