Prunus mume is a Chinese tree species classified in the Armeniaca section of the genus Prunus subgenus Prunus. Its common names include Chinese plum, Japanese plum, and Japanese apricot. The flower, long a beloved subject in the traditional painting and poetry of Sinospheric countries (including China, Korea, Vietnam, and Japan), is usually called plum blossom. 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.
In East Asian cuisine (Chinese, Japanese, Korean and Vietnamese cuisine), the fruit of the tree is used 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.
Prunus mume should not be confused with Prunus salicina, a related species also grown in China, Japan, Korea, and Vietnam. Another tree, Prunus japonica, is also a separate species despite having a Latin name similar to Prunus mume'''s common name.
Prunus mume originated around the Yangtze River in the south of China. It was later introduced to Japan, Korea, and Vietnam. It can be found in sparse forests, stream sides, forested slopes along trails, and mountains, sometimes at altitudes up to , and regions of cultivation.
Prunus mume is a deciduous tree that starts to flower in mid-winter, typically around January until late February in East Asia. It can grow to tall. The flowers are in diameter and have a strong fragrant scent. They have colors in varying shades of white, pink, and red. The leaves appear shortly after the petals fall, are oval-shaped with a pointed tip, and are 4–8 cm long and 2.5–5 cm wide. The fruit ripens in early summer, around June and July in East Asia, and coincides with the East Asian rainy season, the meiyu (梅雨, "plum rain"). The drupe is in diameter with a groove running from the stalk to the tip. The skin turns yellow, sometimes with a red blush, as it ripens, and the flesh becomes yellow.
