A deciduous tree, it includes many varieties of the fruit trees known as plums in English, though not all plums belong to this species. The greengages and damsons also belong to subspecies of ''P. domestica''. Its hybrid parentage is believed to be ''Prunus spinosa'' and ''Prunus cerasifera''. This is the most commonly grown plum at least in Europe, and most prunes (dried plums) are made from fruits of this species. ==Characteristics== Typically it forms a large shrub or a small tree. It may be somewhat thorny, with white blossom, borne in early spring. The oval or spherical fruit varies in size, but can be up to 8 cm across, and is usually sweet (dessert plum), though some varieties are sour and require cooking with sugar to make them palatable. Like all ''Prunus'' fruits, it contains a single large seed, usually called a stone, which is discarded when eating. Plums are grown commercially in orchards, but modern rootstocks, together with self-fertile strains, training and pruning methods, allow single plums to be grown in relatively small spaces. Their early flowering and fruiting means that they require a sheltered spot away from frosts and cold winds. For a full discussion of the fruit, see under the main article Plum. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Prunus domestica」の詳細全文を読む スポンサード リンク
