Abies alba, the European silver fir or silver fir, is a fir native to the of Europe, from the Pyrenees north to Normandy, east to the Alps and the Carpathians, Slovakia, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Serbia, and south to Italy, Bulgaria, Kosovo, Albania and northern Greece.
The leaf are needle-like, flattened, long and wide by thick, glossy dark green above, and with two greenish-white bands of stomata below. The leaf is usually slightly notched at the tip. The conifer cone are long and broad, with about 150-200 scales, each scale with an exserted bract and two winged ; they disintegrate when mature to release the seeds. The wood is white, leading to the species name alba.
In the forest the evergreen tends to form stands with Picea abies, Pinus sylvestris, and Fagus sylvatica. It is closely related to Bulgarian fir ( Abies borisii-regis) further to the southeast in the Balkan Peninsula, Spanish fir ( Abies pinsapo) of Spain and Morocco and Sicilian fir ( Abies 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.
In Italy, the silver fir is an important component of the mixed broadleaved-coniferous forest of the Apennine Mountains, especially in northern Apennine. The fir prefer a cold and humid climate, in northern exposition, with a high rainfall (over 1500 mm per year). In the oriental Alps of Italy, silver firs grow in mixed forests with Norway spruce, beech, and other trees.
Its cone scales are eaten by the of the tortrix moth Cydia illutana, while Cydia duplicana feeds on the bark around injuries or canker.
A resinous essential oil can be extracted. This pine-scented oil is used in perfumes, bath products, and aerosol inhalants. Its branches (including the leaves, bark and wood) were used for production of spruce beer.
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. When cultivated on Christmas Tree plantations, the tree naturally forms a symmetrical conical shape. The trees are full and dense with a resinous fragrance, and are known to be one of the longest lasting after being cut. As well as in its native area, it is also grown on Christmas tree plantations in the northeast region of North America spanning New England in the USA to the Maritime Provinces of Canada.
The wood is strong, lightweight, light-coloured, fine grained, even-textured and long fibred. The timber is mainly used as construction wood, furniture, plywood, pulpwood and paper manufacture.
The honeydew which is produced by sitting on the silver fir is collected by . The resulting honey is marketed as "fir honey".
Alba means 'bright' or 'dead white'.
