Fragaria (/frəˈɡɛəri.ə/)[1] is a genus of flowering plants in the rose family, Rosaceae, commonly known as strawberries for their edible fruits. There are more than 20 described species and many hybrids and cultivars. The most common strawberries grown commercially are cultivars of the garden strawberry, a hybrid known as Fragaria × ananassa. Strawberries have a taste that varies by cultivar, and ranges from quite sweet to rather tart. Strawberries are an important commercial fruit crop, widely grown in all temperate regions of the world.


Strawberries are not berries in the botanical sense.[2] The fleshy and edible part of the "fruit" is a receptacle, and the parts that are sometimes mistakenly called "seeds" are achenes and therefore the true botanical fruits.[2][3]


The Latin name derives from the verb fragro, referring to the aroma of the fruit. Although it is commonly thought that strawberries get their name from straw being used as a mulch in cultivating the plants, the word is possibly derived from "strewn berry" in reference to the runners that "strew" or "stray away" from the base of the plants. David Mikkelson argues that "the word 'strawberry' has been part of the English language for at least a thousand years, well before strawberries were cultivated as garden or farm edibles."[4][5]


There are more than 20 different Fragaria species worldwide. A number of other species have been proposed, some of which are now recognized as subspecies.[6] One key to the classification of strawberry species is that they vary in the number of chromosomes. They all have seven basic types of chromosomes, but exhibit different polyploidy. Some species are diploid, having two sets of the seven chromosomes (14 chromosomes total), but others are tetraploid (four sets, 28 chromosomes total), hexaploid (six sets, 42 chromosomes total), octoploid (eight sets, 56 chromosomes total), or decaploid (ten sets, 70 chromosomes total).

As a rough rule (with exceptions), strawberry species with more chromosomes tend to be more robust and produce larger plants with larger berries.[7]
