Chamaecyparis lawsoniana. PORT ORFORD CEDAR. N. W. North America (incl. coastal N. California)
CUPRESSACEAE (Cypress family)
Known as a splendid timber tree growing close to 100 feet
high on the Oregon-California border, it is, surprisingly,
The fungus Phytophthera ramorum is killing Port Orford cedars in Oregon, a nontrivial matter given that a large tree in 2002 brought as much as $50,000. By 2002 P. ramorum had spread to Big Sur and Berkeley. Sudden oak death syndrome, not previously noted with conifers, was also reported on a redwood. The Irish potato blight reminds us of the social consequences of Phytophthera.
Ray Collett writes that the Port Orford cedar "bears foliage that is pungently fragrant and rather sourish. The wood . . . smells sweet, something like a rose!" (Pacific Horticulture, 67,4, 2006, p. 6.) Make your own judgement: a grove of two dozen old Port Orford cedars can be seen at 776 Dolores Street and there are several, old and new, at Kingscote Gardens, including two narrow old specimens near the pond. In Palo Alto, a specimen to the right of the front door at 1127 Hopkins Avenue can be compared to the incense cedar hedge left of the driveway, and an excellent gold-leaf variety of C. lawsoniana is at 1133 Harker Avenue on the left side.
