It large shrub or tree reaching 6-20 m tall, with a trunk up to 2 m diameter and a broadly conical to rounded or irregular crown. The foliage is strongly aromatic, with a spicy-resinous scent. The leaves are of two forms, juvenile needle-like leaves 8-10 mm long on seedlings and irregularly on adult plants, and adult scale-leaves 0.6-3 mm long on older plants; they are arranged in decussate opposite pairs. It is dioecious with separate male and female plants. The cones are berry-like, 7-12 mm in diameter, blue-black with a whitish waxy bloom, and contain 1-4 seeds; they are mature in about 18 months. The male cones are 3-4 mm long, and shed their pollen in early spring.
