Not too long ago, the genus was reorganized to incorporate simply two species: Deodar (C. deodara) and Lebanon (C. libani).

Blue atlas is now labeled as a subspecies, C. libani ssp. atlantica, if it’s separated in any respect. Some taxonomists suppose the subspecies is redundant.

Cyprus is now labeled as C. libani subsp. (or, generally, var.) brevifolia. 

Blue atlas cultivars are, by far, the preferred in cultivation. You’ll typically nonetheless see them listed on the market beneath the earlier classification, C. atlantica.

To be sincere, the variations between the varied species are minimal. They largely come all the way down to measurement and form.

The opposite matter that provides to the confusion is that Cryptomeria, Chamaecyparis, Calocedrus, and Thuja species are generally referred to as “cedars,” however they aren’t even carefully associated.
