Atlas Cedar

Cedrus atlantica (SEE-drus at-LAN-ti-ka)

Family: Pinaceae Unknown Canopy (>40 ft)

Cedrus atlantica is best used as a specimen tree. This tree is difficult to transplant, is the least cold hardy of the cedars, and should be more widely planted in the south. For planting guidelines, this plant prefers moist, well-drained soil and needs wind protection. In its native habitat, it will form forests on mountainsides. These forests provide a habitat of the endangered primate, Barbary macaque. In its youth, Cedrus atlantica 's form is pyramidal; however, with age, this tree becomes flat topped with broad horizontal branches. Some would even say that this tree is picturesque. Its texture is medium to fine. The growth rate can be up to 24" per year. This long-lived tree has been known to survive up to 150 years. This tree produces an aromatic oil that is a natural insect deterrent. Its harvested wood is commonly used in building furniture and drawers. Human use of this tree brings a sense of danger for its future. Wood harvesting and firewood are the leading cause of the decline of this species. Forests are smaller than then were in the past. However, massive reforestation campaigns are taking place in some regions. Quick ID Hints : similar to C. libani, but has taller crown blue foliage to very blue needles short, stiff, multiple on dwarf shoot all Cedrus genus members have new needles that are born singly on stems needles are triangular to quadrangular in cross-section female wood barrel-shaped cones sit on top of the branches Difficult to transplant Bluish green cedar, 40-60' tall, 30-40' wide. Specimen tree, should be used for nothing less and allowed to develop in an open environment with no competitors. Difficult to transplant, should be moved as container, well drained, moist loamy soil preferred, but can tolerate sandy soil as well, takes full sun, and needs shelter from high winds. Insects, Diseases, and Other Plant Problems: Heavy snowfall can damage or break the branches. Tip blight can occasionally be an issue. Susceptible to Phytophthora and root rotand sooty mold. It needs adequate space in order to properly develop. Its deep taproot makes it difficult to transplant. Cannot grow in full shade.
