Strawberry🍓
Fragaria × ananassa
イチゴ
A cultivated variety also called garden strawberry, bred through hybridization in 18th-century Europe. Introduced to Japan in the late Edo period, numerous Japanese-bred cultivars such as 'Tochiotome,' 'Amaou,' and 'Sagahonoka' have since been developed. Essential as an ingredient for cakes and sweets, its peak season has shifted to winter–spring through forcing culture in vinyl greenhouses.

Evolution Notes
Cultivated strawberry is an octoploid hybrid. It is an excellent example of a Rosaceae accessory fruit (enlarged receptacle), where the true fruits (achenes) correspond to the small pips on the surface.
