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 {{convert|20|to|30|m|ft|sp=us}}, and growing {{convert|1.8|to|4|m|ft|sp=us}} wide. It has dense, dark green upswept needles {{convert|2.5|to|3|cm|in|abbr=on}} long. Seed cones are purplish-brown and {{convert|10|to|14.5|cm|in|abbr=on}} long.

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.
