 Perennial herb, up to 30cm tall, native to Europe and Northern Asia; leaves 3-foliolate, leaflets sessile or central one shortly petiolulate, abaxially greenish, adaxially green, obovate, elliptic or broadly ovate; inflorescence corymbiform, 2-4-flowered, petals white; aggregate fruit ripening red, ovoid.  [[http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200010863]]
-"The wood strawberry Fr.vesca L. differs from the cultivated types in that it contains a very aromatic, plainly recognizable woodstrawberry-like semivolatile compound. It was identified as methylanthranilate, reported previously by Hirvi and Honkanen (1982). This component was detected first in the nearly 50-year-old  “Mieze Schindler” [F.ananassa cultivar]." \\
+"The woodland strawberry was first cultivated in ancient Persia where farmers knew the fruit as Toot Farangi. Its seeds were later taken along the Silk Road towards the far East and to Europe where it was widely cultivated until the 18th century, when it began to be replaced by the garden strawberry, (Fragaria × ananassa), which has much larger fruit and showed greater variation, making them better suited for further breeding."  [[http://en.wikipedia.org/wiki/Fragaria_vesca]]

+Key aroma compounds were DMF (mesifuran), methyl anthranilate, DHF (furaneol), γ-decalactone, the fruit esters methyl butanoate, ethyl butanoate, methyl hexanoate, and ethyl hexanoate, the fruit acids butanoic acid, 2-methyl butanoic acid, and hexanoic acid, and linalool. \\

 The intense aroma of wild species is associated with their high ester and terpene contents... Unlike the cultivated strawberry, all wild types show terpenoid odours like those of terpinen-4-ol... The very pleasant and spicy note of methyl cinnamate was determined only in F. vesca f. alba and in F. moschata ‘Cotta’. \\

-"Strawberry leaves [wild strawberry leaves, Fragariae folium] are rich in condensed tannins and ellagitannins such as agrimoniin and pedunculagin, together with proanthocyanins, flavonoids (quercetin, rutin) and phenolic acids (salicxlic acid, caffeic acid, chlorogenic acid). The rhizomes [Fragariae radix] have a high tannin content." \\
