 in the genus Vaccinium. One characteristic of bilberries is that they produce single or paired berries on the bush instead of clusters, as the blueberry does. Blueberries have more evergreen leaves.

The fruit is smaller than that of the blueberry but with a fuller taste. Bilberries are darker in colour, and usually appear near black with a slight shade of purple. While the blueberry's fruit pulp is light green, the bilberry's is red or purple, heavily staining the fingers and lips of consumers eating the raw fruit. The red juice is used by European dentists to show children how to brush their teeth correctly, as any improperly brushed areas will be heavily stained.

Bilberries are extremely difficult to grow and are thus seldom cultivated. Fruits are mostly collected from wild plants growing on publicly accessible lands, notably Finland, Sweden, Norway, Iceland

, it is an everyman's right to collect bilberries, irrespective of land ownership, with the exception of private gardens and nature reserves. Bilberries can be picked by a berry-picking rake like lingonberries, but are more susceptible to damage. Bilberries are softer and juicier than blueberries, making them difficult to transport. Because of these factors, the bilberry is only available fresh on markets and in gourmet stores, where in the latter they can cost up to 25 Euro per pound. Frozen bilberries however are available all year round in most of Europe.

In Finland, bilberries are collected from forests. They are eaten fresh or can be made in different jams and dishes. The famous one is the bilberry pie (Finnish: mustikkapiirakka, Swedish blåbärspaj).

In Ireland, the fruit is known as fraughan, from the Irish fraochán, and is traditionally gathered on the last Sunday in July, known as Fraughan Sunday.
