Fragaria is the Latin name used in science for the genus of about 20 species of strawberries, plants in the rose family that grow small sweet red fruit. The most well-known and most grown of these species is the strawberry Fragaria × ananassa. The other species are informally known as the wild strawberries. The real fruit of the strawberries are the achenes, which people usually think of as the little seeds around the outside of the larger red "fruit". What people think is the "fruit" is really the swollen stems between these fruit. This kind of fruit, where different ovaries grow into a single larger fruit, is called an "aggregate fruit"
