Incense cedar is primarily found on the western slopes of the Cascade and Sierra Nevada mountain ranges, at altitudes of 300 to 2,800 meters (1,000 to 9,200 feet). The tree is well-adapted to the warm, dry summers and relatively mild winters of southwest Oregon, and it can tolerate a variety of ecological conditions, from riparian (stream-side) environments to dry sites.
The incense cedar tree can grow to impressive heights, typically reaching 30 to 45 meters (100 to 150 feet) tall, and up to 5.5 meters (18 feet) in diameter. The largest known incense cedar is located in the Marble Mountain Wilderness of Northern California, boasting a circumference of 469 inches and a height of 165 feet. The tree has a straight trunk with reddish, furrowed bark, and its spreading branches end in sprays of branchlets covered with dark green leaves. The foliage and wood of the incense cedar contain resins, giving off a spicy fragrance when crushed, reminiscent of a mix of pencil shavings and parsnips.
The wood of the incense cedar is fine-grained, easily worked, aromatic, and generally resistant to decay and insects. Native Americans utilized incense cedar leaves in various ways, including as a decoction for stomach ailments, a vapor infusion for colds, and even as a food spice. The bark fiber was also used for basketry, twine, friction fire-making, and fuel, while the branches found a purpose as filters or brooms. Today, the timber is commonly used for carpentry, pencils, storage chests, interiors, and fence posts.
Incense cedar is a drought-tolerant species, capable of closing its leaf pores (stomata) to prevent water loss. It prefers freely draining, slightly acidic soil and is a slow-to-moderate grower that can tolerate shade but thrives in full sun. Regular irrigation is necessary during the first few years of establishment. Incense cedar is also grown ornamentally in Europe and the eastern United States, valued for its ability to withstand summer heat, low water requirements, and adaptability to poor soils.
