BLUEBERRIES

 

Characteristics of blueberries

Blueberries (Vaccinium), also called bilberries are plants shrub of the Ericaceae family, within which we have other shrubs such as the strawberry tree (Arbutus unedo), bearberry (Artostaphylos uva-ursi) or heather (Erica)

The common blueberry (Vaccinium myrtillus) is a deciduous plant which is between 20 and 60 cm in height. Stems light green, hairless, with four marked angles. Leaves up to 3 cm long, alternate, bright green, oval, with fine teeth, leathery texture and acute apex. Flowers of 4-6 mm in diameter lantern-shaped, pink or green-pink, single or in groups of two, that hang from the axils of the leaves. Berry fruit is about 5 mm, black, blue, covered with purple hairs, rounded shape with a flat end. It blooms from April to June and fruits appear from July to August.

The scientific name of this plant responds to the shape of the leaves that resemble those of the myrtle, so in the sixteenth century was given the name Myrtillus (small myrtle). In the name of the genus Vaccinium, is not clear whether it was the Roman poet Virgil named so because it is a species that was often a source of food for cows, or the name derives from "bacca" which in Latin, means “berry.”

Bilberry is a plant from northern Europe, and it is very common in Scandinavia, where it forms a dense carpet on the floor covering taiga forests of spruce (Picea abies). The importance of this fruit in this area is such that any person has the liberty to collect it even if the forest where it is belongs to other people.

It is also common throughout the boreal zone of Asia. It appears almost everywhere in Europe, mainly in acid soils of temperate forests, bogs, heaths or swamps. In Europe it is especially abundant in Ireland, Scotland and Poland. In Iceland it is practically the only wild fruit to be found, along with some other ericaceous of the genus empetrum. As we move south, we have to look for it in moist soils in mountain areas.

 

Uses of blueberries

Normally this plant is usually planted for its production but is collected directly from wild plants. Blueberries can be eaten fresh when fully ripe and have lost their initial roughness. Eaten like this, they are sweet and astringent. Another way to use them is to drink its juice. There are many companies on the market that sell blueberry juice. It is very common to make jams and cakes with these fruits.

The fruit of cranberry and especially its leaves are used as a medicinal plant for the treatment of many diseases, especially all those related to the urinary tract. (See more information in the listing above)
