Genus:Calocedrus

Species:decurrens

Family:Cupressaceae

This conifer not only features striking, aromatic foliage but also showcases intriguing gray-brown bark that peels away in layers, along with prominent male and female cones. Its overall shape is broadly conical, characterized by branches that spread outward. The branchlets are flattened and culminate in dense, fan-like clusters. When crushed, the dark green leaves release a pleasant fragrance. The small male cones are yellow, while the female cones take on a cylindrical shape, consisting of six paired, flattened, pointed scales. In early autumn, as the female cones begin to open, they take on a shape reminiscent of a duck's bill. These cones mature in late summer at lower elevations, with those at higher elevations ripening about a month later.

This tree is adaptable to various soil types, though it thrives best in moist, well-drained, and fertile conditions. Notably, it is resistant to winter burn.

However, it may face challenges such as heart rot and rust, and it can be quite difficult to transplant successfully.
