Chamaecyparis lawsoniana, known as Port Orford cedar[2] or Lawson cypress, is a species of conifer in the genus Chamaecyparis, family Cupressaceae. It is native to Oregon and northwestern California, and grows from sea level up to 4,900 feet (1,500 m) in the valleys of the Klamath Mountains, often along streams. A large evergreen tree, specimens mature up to 200 ft (61 m) tall or more, with trunks 4–7 ft (1.2–2 m) in diameter, exceptionally 8–9 ft (2.4–2.7 m). The bark is silver-brown, vertically furrowed, and 6–10 inches (15–25 cm) thick near the base. The foliage is arranged in lacy, flat sprays with a feathery appearance, usually somewhat glaucous (i.e. blue-green) in color. The leaves are scale-like, 1�8–3�16 inch (3–5 mm) long, with narrow white markings on the underside, and produced on somewhat flattened shoots. The foliage gives off a rather pungent scent, not unlike parsley. The seed cones are globose, 9�32–9�16 inch (7–14 mm) in diameter, with 6–10 scales, green at first, maturing brown in early fall, 6–8 months after pollination. The male cones are 1�8–5�32 inch (3–4 mm) long, dark red, turning brown after pollen release in early spring. The seeds fall quickly and can float on water. Old specimens lack branches near the base and often have dead tops. They can live up to about 600 years of age.
