Atlas Cedar is a species of picturesque coniferous tree found in the Atlas Mountain Range of Morocco and Algeria at an altitude of 1,370-2,200m. It has a loose pyramidal form when young, and its striking green or bluish-green foliage, along with its long branches, spread rapidly, becoming flat-topped with age. When given enough room to grow freely, it can reach up to a height of 40m, and its crown can spread up to 12m.
