Fragaria vesca, commonly known as Woodland Strawberry occurs naturally throughout the Northern Hemisphere. Other names for this species include the Wild Strawberry, European Strawberry and Alpine Strawberry the latter usually in reference to the cultivated varieties such as Fragaria vesca 'Semperflorens'.

Like all strawberries, it is in the family Rosaceae; its fruit is more technically known as an accessory fruit, in that the fleshy part is derived not from the plant's ovaries (achenes) but from the peg at the bottom of the bowl-shaped hypanthium that holds the ovaries.

[edit] Polyploidy

All strawberry species have a base haploid count of seven chromosomes; Fragaria vesca is diploid, having two pairs of these chromosomes for a total of 14.

[edit] Ecology

Typical habitat is along trails and roadsides, embankments, hillsides, stone and gravel laid paths and roads, meadows, young woodlands, sparse forest , woodland edges and clearings. Often plants can be found where they do not get sufficient light to form fruit. The fruit are eaten and the achenes in this way spread by numerous mammals and birds.

[edit] Cultivation and uses

F. vesca from Sweden, threaded on a straw. The plant behind is not a strawberry plant.

Evidence from archaeological excavations suggests that fragaria vesca has been consumed by humans since the Stone Age.^[1] The Woodland Strawberry was widely cultivated in Europe until the 18th century, when it began to be replaced by the Garden Strawberry (Fragaria x ananassa), which have much larger fruit and showed greater variation, making them better suited for further breeding. Woodland Strawberry fruit is strongly flavored, and is still collected and grown for domestic use and on a small scale commercially for the use of gourmets and as an ingredient for commercial jam, sauces, liqueurs, cosmetics and alternative medicine. In Turkey several 100 tons of wild fruit are harvested annually, mainly for export.^[2]

Most of the cultivated varieties are by botanists usually set to the subspecies Fragaria vesca 'Semperflorens' and they are usually called Alpine Strawberries. They have in common that they rarely form runners (instead forming multiple crowns in a cluster), fruit over a very long timeperiod and are usually propagated by seeds or division of the plants. Some cultivars have fruit that are white, or yellow when fully ripe, in addition to the normal red. Plants tend to lose vigour after a few years. Cultivars that form stolons are often used as groundcover, while cultivars that do not may be used as border plants. Some cultivars are bred for their ornamental value. There also exist hybrid cultivars from crosses between Woodland Strawberry and Garden strawberry.

The alpine strawberry is used as an indicator plant for diseases that affect the garden strawberry. It also finds use as a genetic model plant for garden strawberry and the Rosaceae family in general, due to its:

very small genome size
short reproductive cycle (14–15 weeks in climate-controlled greenhouses)
ease of propagation

F. vesca is sometimes used as an herbal medicine; an herbal tea made from the leaves, stems, and flowers is believed to aid in the treatment of diarrhea.
