Chamaecyparis lawsoniana

Chamaecyparis lawsoniana Chamaecyparis lawsoniana (aka Port Orford cedar, Port-Orford white-cedar, Oregon-cedar, Lawson false-cypress, Lawson cypress, and Lawson's cypress) is a conifer species native to the Pacific Northwest. The species, belonging to the cypress family Cupressaceae, yields an outstandingly valuable lumber, which has a ginger-like fragrance. Because of the remarkable straightness of its wood grain, C. lawsoniana is a preferred wood for the manufacture of Arrow#Shaft arrow shafts and, with its strength and tonal qualities, is often used in making String instrument stringed instruments.

The majority of trees grow below 3000 feet and are at their best growing about 3 to 15 miles from the coast. It is sometimes found associated with spruce, Douglas fir, Tsuga hemlock, and Thuja thuya, but often forms unmixed colonies.

Cupressus Lawsoniana.—This we consider one of the greatest acquisitions that has been made for many years to our list of hardy evergreens. Its foliage resembles the Thuja aborvitæ, but its habit is that of the Tsuga hemlock. As a lawn tree, or for association and planting near water, or in cemeteries where there is room, its beauty of foliage and form renders it in every way desirable. There is a variety of this called Pyramidalis, that is more dense and upright, but to us not as beautiful.

It is a highly valued Lumber timber tree because of the durability, excellent machinability, light weight, strength, and shock resistance of the wood. It is also valued worldwide as an Ornamental plant ornamental. G. L.

Once a tree near a stream is infected the pathogen spreads rapidly down the stream. Drew E.

In 1997, the United States Forest Service started a Port-Orford-cedar breeding program to increase resistant varieties of this tree to be replaced in areas of its native range.
