On the back of its foliage, the Turkish fir has a silvery hue, exposed as a result of the upward growth habit of its needles. This characteristic makes the tree, along with its pleasant fragrance, a common ornamental.

Turkish fir is typically a narrow and conical tree, with a mature height of 20 to 30 meters (60 to 100 feet), and growing 1.8 to 4 meters (6 to 28 feet) wide. It has dense, dark green upswept needles 2.5 to 3 cm (1 to 1.2 inches) long. Seed cones are purplish-brown and 10 to 14.5 cm (4 to 5.8 inches) long.[2]

Its native range is in northwestern Turkey, including the western Pontic Mountains south of the Black Sea, and Uludağ and other mountains southeast of the Sea of Marmara.[2]
