Plum

A plum is a fruit of some species in Prunus subg. Prunus. Dried plums are often called prunes, though in the United States they may be labeled as 'dried plums', especially during the 21st century. Plums are likely to have been one of the first fruits domesticated by humans, with origins in East European and Caucasian mountains and China. They were brought to Britain from Asia, and their cultivation has been documented in Andalusia, southern Spain. Plums are a diverse group of species, with trees reaching a height of 5–6 metres when pruned. The fruit is a drupe, with a firm and juicy flesh.
