The European blueberry (lat. Vaccinium myrtillus), also known as bilberry, blaeberry, wimberry, and whortleberry, is a shrub that is native to Northern Europe and in temperate and cold regions. In Greece, bilberries grow on the mountains of Macedonia and on Mount Olympus, in coniferous forests always in cool locations, ravines, and forest glades, and at an altitude of 1,500-2,100 meters.

The fruit of the bilberry has a dark blue color and sour taste and it is edible; it is consumed raw or cooked.

Bilberries – which are native to Europe – are usually confused with North American blueberries.
