The strawberry (Fragaria) is a genus of plants in the family Rosaceae, and the fruit of these plants. There are more than 20 named species and many hybrids and cultivars. The most common strawberries grown commercially are cultivars of the Garden strawberry, Fragaria × ananassa. Strawberries are a valuable source of vitamin C. See Garden Strawberry for information about the fruit as a food.
Morphology
The strawberry is an accessory fruit; that is, the fleshy part is derived not from the ovaries which are the "seeds" (actually achenes) but from the peg at the bottom of the hypanthium that held the ovaries. So from a technical standpoint, the seeds are the actual fruits of the plant, and the flesh of the strawberry is modified receptacle tissue. It is whitish-green as it develops and in most species turns red when ripe.
