A plum is a fruit of the subgenus Prunus. The plant is best described as small tree or large shrub. It is widely cultivated at commercial scale in the United States, Europe, Japan and China. Several cultivars of plums are grown all over the world which differ in their color, size and growth characteristics. Generally, each variety of the plum tree bears numerous, almost uniform sized berries between May and October months.
Plums are low in calories (46 calories per 100 g) and contain no saturated fats; however, they hold numerous health promoting compounds, anti-oxidants, minerals, and vitamins.
