Fully grown, Atlas Cedar is a large tree, 30–35 m (rarely 40m) tall, with a trunk diameter of 1.5–2 m.
Cedrus atlantica(Atlas Cedar) is common in cultivation as an large ornamental tree In gardens the glaucous forms are planted as ornamental trees, distinguished as the Glauca Group. There are also fastigiate, pendulous, and golden-leaf forms in cultivation. The Atlas Cedar is useful in cultivation because it is more tolerant of dry and hot conditions than most conifers.
Many (but far from all) of the cultivated trees have glaucous (bluish) foliage, more downy shoots, and can have more leaves in each whorl; young trees in cultivation often have more ascending branches than many cultivated Cedrus atlantica.
An Atlas Cedar is planted at the White House in Washington, DC. President Jimmy Carter ordered a tree house built within the Cedar for his daughter Amy. The wooden structure was designed by the President himself, and is self-supporting so as not to cause damage to the tree.[
C. atlantica ‘Glauca group’ has gained the Royal Horticultural Society’s Award of Garden Merit (AGM).
