There are various types of plums. Actually, there are over 2,000 varieties which exist. Plums have six general categories and these are: Damson, Japanese, Wild, European/Garden, American, and Ornamental. Usually, plums have the round, oval, or heart-shaped appearance.
Plums’ skin may come in purple, red, green, amber, yellow, or blue-black. Then, as for their flesh, the color may be green, orange, pink, and yellow. The plum season is from May to October. 
Since there are a huge variety of plums, it follows that these types also have different places of origin as well as heritages. For example, the European plum was discovered around 2,000 years ago and thought to originate near the Caspian Sea. During the Ancient Roman times, plums were already present with over 300 varieties. In the 17th century, European plums were introduced into United States.
Another variety of plums, the Japanese plums, had its origin way back in China. The name was just obtained from the country where its cultivation and development took place. Then, in the late 19th century, it was also brought to United States. Nowadays, the top country producers of plums are China, Russia, Romania, and United States. 
When interested in planting plums, it should be remembered that it will be required to plant more than one type of plum tree. This is due to the fact that many types need cross-pollination to allow production of fruit. However, there are also plum varieties which can produce fruits by themselves. A perfect example is the European type, Stanley. It is known to be self-fertile. Thus, no cross-pollination is needed.
Also, pick out the proper location in which the plum tree is to be planted. As for the European types, they can grow in most regions in US. The Japanese varieties can be planted where the peach trees can grow. Then, the American hybrids are well suitable to be planted in regions where the Japanese or European types can flourish. Moreover, the land that should be used in planting plum trees should be moderately fertile soil in full sun and well-drained. Avoid growing these kinds of trees in low areas where there may be frost settlement. 
The time for harvesting plums is when it is ripe. Ripe plums can be identified by gentle pressure application with fingers. When the fruit’s skin feels soft, it is ready for harvesting. Also, the fruit must come off of the tree easily with a slight twist.
