Edible: Botanically the "strawberry" is an aggregate accessory fruit: the receptacle becomes fleshy after flowering and the true fruits are the small nutlets sitting on it. Ripening from June to late July, the fruits are only one to two centimetres across but far more aromatic than any garden strawberry, with around 60 milligrams of vitamin C per 100 grams. They are best eaten fresh, but also work as jam and jelly, juice, syrup, fruit wine and sparkling wine, liqueur and fruit spirit, vinegar, punch, ice cream and cake topping. One detail is worth knowing: the green nutlets contain a bitter principle that only emerges after some minutes of cooking — preserve made purely from wild strawberries can therefore taste bitter, whereas mixed with other fruit it does not. The young leaves make a mild everyday tea.

Other uses: Beyond its fruit, the wild strawberry is above all useful as a covering plant. Its long runners close open ground within a few years, hold soil on banks and suppress weeds without competing seriously with woody plants for water — which is why it is a standard component of the herb layer under fruit trees and berry bushes. For larger areas the Fragaria x vescana hybrids of garden and wild strawberry are also an option: they run strongly, are very robust, cover ground well and carry medium-sized, soft fruit with intense wild-strawberry aroma. They are the basis of the classic "strawberry meadow" that bears from June to August.

Site: The wild strawberry is the classic ground cover for semi-shaded woodland edges, path margins and banks — in sun it tastes better, in shade it stays leafy and flowers little. It travels by runners and naturalises readily; in a perennial bed it pushes into its neighbours, while under shrubs and around tree bases that is exactly its advantage. It keeps the soil covered, prevents erosion on slopes and provides one of the most species-rich pollinator resources of early summer. In damp, shaded, still positions slug pressure rises sharply, and birds harvest the fruit alongside you — if you want neither, plant it airy and open. Care: Very undemanding. A mulch of leaves or grass clippings keeps the soil moist and the fruit clean; it needs little feeding, and too much nitrogen goes into leaves. Thin the old foliage after harvest to keep mildew and grey mould in check. Renewal is the key point: after three or four years individual plants lose vigour, so move fresh runners to a new spot. Runnerless alpine strawberries must be divided or re-sown instead. Water in dry spells, otherwise the fruit stays small and flavourless.

The simplest way to propagate wild strawberry is by runners: detach rooted daughter plants in spring or after harvest and replant them at once. To cover larger areas, take several runners per mother plant. Sowing is the route for runnerless alpine strawberries and for wild provenances: the tiny nutlets are pressed in but not covered, and germinate in light and mild warmth over two to four weeks, far more evenly after a cold spell. Dividing older clumps also works and is the reliable method for cultivars, since seedlings do not come true.

The wild strawberry is among the most valuable herb-layer plants there is. NaturaDB records 45 wild bee species on it, more than 40 of which collect pollen — above all mining bees (Andrena) and furrow bees (Lasioglossum). The nectar lies open and easily reached, so besides honeybees, bumblebees and wild bees, butterflies, beetles and flies also visit. As a larval food plant the leaves serve 22 butterfly and moth species, among them the grizzled skipper (Pyrgus malvae) and several geometrids and noctuids. Birds and small mammals eat the fruit and pass out the nutlets, spreading the plant; in addition the runners and the heavy fruit move it short distances on its own. The dense leaf mat gives ground beetles, spiders and amphibians cover and moisture.

Notable: archaeologically documented as a gathered fruit since the Stone Age, praised by Ovid, Pliny+Virgil; field-grown from the 14th century on without the fruit ever getting bigger; displaced by the garden strawberry in the 18th century → back-breeding produced the alpine strawberry; legend has Mary descending once a year to gather strawberries for dead children; in Grimm a girl in a paper dress must find strawberries in midwinter;

Eurasia: Europe and northern Asia. The wild strawberry occupies almost the whole European continent from Scandinavia to the Mediterranean and extends through temperate Asia to Siberia; closely related subspecies also occur in temperate North America. It is native and common throughout Central Europe and climbs to 1,750 metres on the Aggenstein in the Allgäu Alps. Its cultivated form is the alpine or everbearing strawberry (var. semperflorens), while the large-fruited garden strawberry arose at Versailles in the 18th century from two American species and displaced the wild strawberry from field cultivation. Escaped garden forms are barely distinguishable from wild populations.

The wild strawberry is a plant of transitional ground: open broadleaf and conifer woodland, woodland edges, path margins, banks and above all clearings. In Central Europe it is a character species of the Epilobietea, the clearing communities, and also occurs in fringe communities of the Alliarion and Trifolion medii — it follows disturbance and retreats once the canopy closes. It needs fresh, well-drained, nutrient- and humus-rich soil and tolerates no waterlogging. Full sun to partial shade suits it; in deep shade it barely flowers. Through its long runners it forms dense, spreading mats that hold open soil in place until woody plants grow back.
