Noteworthy Characteristics
Abies nordmanniana, commonly called Caucasian fir or Nordmann fir, is native to the Caucasus Mountains. This is a dense, pyramidal conifer that typically grows to 50' tall and 20' wide in cultivation, but may reach 200' tall in its native habitat. Trees are typically branched to the ground. Branches are densely clad with flattened, glossy dark green needles (to 1 1/4” long). Needles have two white bands underneath. Bark is charcoal gray. Cylindrical seed cones (to 6" long) are dark reddish-brown. As is distinctive with the firs, the cones appear upright on the branches. Cones disintegrate (scales drop) after the seeds ripen.
Genus name is an ancient Latin name for a tree described by Pliny around 77 A.D.
Specific epithet honors Alexander Davidovic von Nordmann (1803-1866), Finnish naturalist, who discovered this species growing in the Caucasus in 1836-1837.
