In a broad sense, strawberry refers to perennial plants of the Rosaceae family, such as Rubus arbutus, Rubus nigricans, and Rubus arbutus, as well as deciduous shrubs (Rubus species) such as Rubus arbutus, Rubus nigricans, Rubus arbutus, Rubus arbutus, and Rubus arbutus. All of these are wild and non-toxic, and many are edible. In general, strawberry refers to the cultivated species, Rubus arbutus. It is said to be native to South America (the Chiloe Island in Chile), but was brought to Japan by the Dutch during the Tenpo era (around 1840). It grows by sending out numerous runners from an underground rhizome, and produces dense basal leaves with long stalks and trifoliate compound leaves. It produces white five-petaled flowers from spring to summer. The fruit is a false fruit with an enlarged flower bed, and the sesame-like grains on the surface are the true fruit, which are modified pistils. In addition to being eaten as is, the fruit is processed into ingredients for jams and sweets. It has been improved in various countries around the world, and there are many varieties.

イチゴは広義にはバラ科のヘビイチゴ,オヘビイチゴ,シロバナノヘビイチゴなどの多年草や,カジイチゴ,ナワシロイチゴ,フユイチゴなどの落葉小低木 (キイチゴ類) をさす。いずれも野生種で無毒,食べられるものも多い。また一般には,イチゴといえば栽培種のオランダイチゴ (ストロベリー) をさす。これは南アメリカ (チリのチロエ島) 原産といわれるが,日本には天保年間 (1840頃) にオランダ人によってもたらされた。地下の根茎から多数のランナー (走出枝) を出してふえ,長い柄のある3出複葉の根生葉を密につける。春から夏にかけて,白色5弁の花をつける。果実は花床が肥大した偽果で,表面についているゴマのような粒が,めしべの変化したほんとうの意味の実である。果実をそのまま食べるほか,ジャムや菓子の原料に加工する。世界各国で改良され,多数の品種がある。
