Plum has many species, and taxonomists differ on the count. Depending on the taxonomist, between 19 and 40 species of plum exist. From this diversity only two species, the hexaploid European plum (Prunus domestica) and the diploid Japanese plum (Prunus salicina and hybrids), are of worldwide commercial significance.
Plum trees are grown on every continent except Antarctica. They are most commonly planted in temperate zones.
The average lifespan for cultivated plum trees is 10 to 15 years.
The commercially important plum trees are medium-sized, usually pruned to 5–6 meters (16-20 feet) height. Without pruning, the trees can reach 12 meters (39 feet) in height and spread across 10 meters (33 feet).
Some plum varieties have leaves that are oblong in shape with a pointed tip while others have oval leaves that are serrated on the edges. Leaves are usually 5 to 10 centimeters (2 to 4 inches) long and green in color.
The flower buds on most varieties are borne on short spurs or along the terminal shoots of the main branches. Each bud may contain from one to five flowers, two or three being most common, and often give an appearance of densely packed, showy flower clusters when the trees are in full bloom.
Fruits are usually of medium size, between 2.5 and 7.5 centimeters (1 and 3 inches) in diameter, globose to oval. The flesh is firm and juicy. The fruit’s peel is smooth, with a natural waxy surface that adheres to the flesh. The color of the peel varies from bluish-black to red, purple, green or yellow.
The plum is a drupe or stone fruit, meaning its fleshy fruit surrounds a single hard seed.
