my favourite fruit~strawberry~

Garden strawberries are a common variety of strawberry cultivated worldwide. Like other species of Fragaria (strawberries), it belongs to the family Rosaceae. Technically it is not a fruit but a false fruit, meaning the fleshy part is derived not from the plant's ovaries (achenes) but from the peg at the bottom of the bowl-shaped hypanthium that holds the ovaries.
The Garden Strawberry was first bred in Europe in the early 18th century. This represents the accidental cross of Fragaria virginiana from eastern North America, which was noted for its flavor, and Fragaria chiloensis from Chile, which was noted for its large size.

Strawberry cultivars vary remarkably in size, colour, flavour, shape, degree of fertility, season of ripening, liability to disease and constitution of plant. Some vary in foliage, and some vary materially in the relative development of their sexual organs. In most cases the flowers appear hermaphroditic in structure, but function as either male or female.

Strawberries are picked at their peak and do not ripen after harvesting, so select berries that are bright red in color that have a natural sheen with fresh looking green caps. Avoid strawberries with green or white tips. If boxed in cardboard or other paper products, pay particular attention to any dampness and/or staining, especially at the bottom of the container. This may be evidence of significantly overripe, even decaying fruit. Store strawberries in the refrigerator in a single layer on a paper towel in a moisture proof container. Eat them within 48 - 72 hours, or freeze them. Do not wash them until you are ready to eat them, or they will become mushy and moldy
