  • The Cedrus genus was formerly considered to include four species, but some authorities have reduced it to two, C. deodara of the Himalayas and C. libani (Cedar of Lebanon) of the Mediterranean.  C. atlantica, the most common species used in landscaping is now considered to be a subspecies of C. libani (i.e., C. libani ssp. atlantica), or even just synonymous (van Gelderen and van Hoey Smith, 1996).  Hence the common glauca (bluish) form may be named C. libani ssp. atlantica 'Glauca' or possibly even C. libani 'Glauca'.  However, it is likely that this popular tree will continue to be offered for some time in the nursery trade as C. atlantica 'Glauca'.
