Cedrus atlantica belongs to a genus that demands long perspectives. In its native Atlas Mountains, spanning Morocco and Algeria, it forms whole forests on high slopes at elevations where thin air and bright light have sculpted its character over millennia. Brought into cultivation, it grows at a satisfying pace — up to two feet per year — and begins pyramidal, then slowly widens into the flat-topped, horizontally branched silhouette that defines a mature specimen. The blue-green needles carry a waxy sheen, and the barrel-shaped cones perch upright on the upper branches like small monuments. Trees have been known to persist 150 years.

At 40 to 60 feet tall and 30 to 40 feet wide at maturity, it is a tree that requires a committed site — open ground, good drainage, protection from strong wind, and no competition at close range. It transplants poorly once established, so container planting into its permanent position is the right approach. The aromatic oil in its wood and needles deters insects naturally. In its native range the Barbary macaque, one of the few primates found in Africa north of the Sahara, depends on these forests for habitat, which gives the Atlas cedar a weight beyond its ornamental value.
