Plum: Prunus mume is an Asian tree species. This distinct tree species is related to both the plum and apricot trees. Although generally referred to as a plum in English, it is more closely related to the apricot. The fruit of the tree is used in Chinese, Japanese and Korean cooking in juices, as a flavouring for alcohol, as a pickle and in sauces. It is also used in traditional medicine. The tree's flowering in late winter and early spring is highly regarded as a seasonal symbol.
