Plums

Plums are likely to have been one of the first fruits domesticated by humans, with origins in Eastern Europe, the Caucasus 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 (16–20 ft) when pruned. The fruit is a drupe, with a firm and juicy flesh. Plums can be eaten fresh, dried to make prunes, used in jams, or fermented into wine and distilled into brandy. Plum seeds (also called kernels) contain the cyanide-like poison, amygdalin, a cyanogenic glycoside.
