Blueberry (wild – Myrtillus)/Bilberry

Wild blueberry (Myrtillus) / Bilberry

Bilberries (/ˈbɪlbəri/), or occasionally European blueberries), are a primarily Eurasian species of low-growing shrubs in the genus Vaccinium (family Ericaceae), bearing edible, dark blue berries. The species most often referred to is Vaccinium myrtillus L., but there are several other closely related species.

Bilberries – which are native to Europe – are different from North American blueberries, although the species are closely related and belong to the same genus, Vaccinium. Bilberry are non-climacteric fruits with a smooth, circular outline at the end opposite the stalk, whereas blueberries retain persistent sepals there, leaving a rough, star-shaped pattern of five flaps. Bilberries grow singly or in pairs rather than in clusters, as blueberries do, and blueberries have more evergreen leaves. Bilberries are dark in colour, and usually appear near black with a slight shade of purple.

Bilberries and blueberries contain diverse anthocyanins, specifically anthocyanidins, including delphinidin and cyanidin glycosides. While blueberry fruit pulp is light green in color, bilberry is red or purple. The high anthocyanin content may cause staining of the fingers, lips, and tongue of consumers.
