Noteworthy Characteristics

Calocedrus decurrens, commonly called incense cedar, is an aromatic evergreen conifer with upright branching that is narrow-columnar in youth but may broaden with age to conical sometimes with a rounded crown. It is native to the Cascades, Sierras and coastal ranges, usually scattered in mixed conifer forest on western slopes, from Oregon to California, southwestern Nevada and northern Baja California. In the wild, it may grow to 100-150’ and live to 1000+ years. In cultivation, it typically grows shorter to 30-50’ tall. Flattened branchlets in fern-like sprays are covered with overlapping, lustrous, rich green, scale-like foliage in whorls of four. Foliage has an incense-like aroma when crushed. Reddish-brown, deeply-furrowed, scaly bark appears on mature trees. Solitary fruiting cones (to 1” long) ripen in summer at the branchlet ends. Although small, cones are very distinctive and are commonly described as resembling duckbills when they open to release their seed. Synonymous with and formerly known as Libocedrus decurrens.

Genus name comes from the Greek words kalos meaning beautiful and cedrus meaning cedar tree.
