It is conical in shape when younger and is a more open shape when mature. It grows to 40m in height. The bark is silvery grey with deep cracks. The leaves of the Atlas cedar are 2.5 cm long, pointed, usually 4 sided and dark green to glaucous blue in colour. The female cones are 6–10 cm long, barrel-shaped, green when young, becoming brown as they mature.
