Calocedrus decurrens, commonly known as the California Incense Cedar, is a large coniferous tree native to western North America. It grows at altitudes ranging from 160 to 9500 ft and is often simply called 'Incense Cedar.' The leaves, when crushed, emit an aroma akin to shoe-polish. The wood of the tree is the primary material used in making wooden pencils, as it is soft and sharpened easily without forming splinters. Native Americans of California widely used the tree in traditional medicine, basket-making, hunting bows, and building materials. The tree is highly valued for its ornamental properties and is widely cultivated in gardens and parks across California and other colder regions.
