About

Vaccinium myrtillus is a holarctic species of shrub with edible fruit of blue color, known by the common names bilberry, blaeberry, and whortleberry. It is more precisely called common bilberry or blue whortleberry to distinguish it from other Vaccinium relatives.

Where it grows

Vaccinium myrtillus is a Holarctic species native to almost every country in Europe, north and central Asia, Japan, Greenland, Western Canada, and the Western United States. Within Europe it is only absent from Sardinia, Sicily, the European portion of Turkey, Crete, the Aegean Islands, Cyprus, Crimea, and southern European Russia. It occurs in the acidic soils of heaths, boggy barrens, moorlands, degraded meadows, open forests at the base of pine and mountain spruce forests, and parklands, slopes, and moraines at elevations up to 2,350 m (7,710 ft).
