Where it grows: Along the Pacific Coast from Coos Bay, Oregon to the Klamath River in California, extending to 5000 ft. in the Siskiyous.  

Locations: At the Oregon Caves National Monument on the Big Tree Trail (42.10124 -123.40306). You can find several plantings in Portland's Forest Park, for example at the top of the Dogwood trail (45 32.397 -122 43.967) and at miles 14.3 and 16.6 on the Wildwood Trail.

Uses: Current uses are similar to Western Red Cedar in decking and fencing. However, limited supply and popularity in Japan contribute to high prices. Cultivars are popular ornamentals.

Names: The scientific name honors Peter Lawson, who first introduced Port Orford Cedar cultivars. Other common names: White Cedar, Oregon Cedar.

Note that Port Orford Cedar is not a true cedar. That is, its genus is not Cedrus, the genus of the true cedars from the middle-east.
