Abies alba, the silver fir or European silver fir,[2] is a fir native to the mountains of Europe, from the Pyrenees north to Normandy, east to the Alps and the Carpathians, and south to southern Italy and northern Serbia.[1]

A. alba is a large evergreen coniferous tree growing to 40–50 m (exceptionally 60 m) tall and with a trunk diameter of up to 1.5 m. The largest measured tree was 68 m tall and had a trunk diameter of 3.8 m. It occurs at altitudes of 300-1,700 m (mainly over 500 m), on mountains with a rainfall of over 1,000 mm.
The leaves are needle-like, flattened, 1.8–3 cm long and 2 mm wide by 0.5 mm thick, glossy dark green above, and with two greenish-white bands of stomata below. The tip of the leaf is usually slightly notched at the tip. The cones are 9–17 cm long and 3–4 cm broad, with about 150-200 scales, each scale with an exserted bract and two winged seeds; they disintegrate when mature to release the seeds. The wood is white, leading to the species name "alba".[2]
It tends to forms woods with other firs and beeches.[2] It is closely related to Bulgarian Fir (Abies borisiiregis) further to the southeast in the Balkan Peninsula, and Sicilian Fir (A. nebrodensis) in Sicily, differing from these and other related Euro-Mediterranean firs in the sparser foliage, with the leaves spread either side of the shoot, leaving the shoot readily visible from above. Some botanists treat Bulgarian Fir and Sicilian Fir as varieties of Silver Fir, as A. alba var. acutifolia and A. alba var. nebrodensis respectively.
Silver Fir is an important component species in the Dinaric calcareous Silver Fir forest in the western Balkan Peninsula.
Its cone scales are used as food by the caterpillars of the tortrix moth Cydia illutana, while C. duplicana feeds on the bark around injuries or canker.
A resinous essential oil can be extracted. This pine-scented oil has soothing qualities, and is used in perfumes, bath products, and aerosol inhalants.[2]
Silver Fir is the species first used as a Christmas tree, but has been largely replaced by Nordmann Fir (which has denser, more attractive foliage), Norway Spruce (which is much cheaper to grow), and other species. The wood is moderately soft and white, used for general construction and paper manufacture.
