Widely dispersed in Europe into the Caucasus, but not native to Great Britain. Big shrub to multiple-stemmed tree with a compact, irregular crown. The trunk and the young twigs are grey. In contrast with A. glutinosa, A. incana has no sticky parts. The alternate green leaves are ovate and acute-pointed, they have serrated margins and hairy to velvety undersides. Buds are short stalked. The inflorescence with ± 0.5 cm female catkins and ± 7 cm purplish male catkins with yellow pollen, is inconspicuous. The grey brown strobiles appear in September and decorate the tree all winter. A. incana roots fairly deep, but shallower than A. glutinosa and is used in forestry as a producer of nitrogen. Intolerant to hard surfaces.
