Olive trees, also known as 'Olea europaea,' are one of the oldest and foremost vital fruit trees in history. Fruit tree culture has been closely connected to the increase and fall of Mediterranean empires, as well as different advanced civilizations throughout the ages. Production from olive trees offered great wealth and provided future food to a number of recognized civilizations. Agricultural nations became steady societies, followed by a secure anticipation from past experience of an endless food and vegetable oil supply. Dependable fruit and vegetable oil production implies that olive trees helped encourage a stable society and a peaceful surroundings. That stability extended for several years, since most ancient seedling olive trees needed eight or more years before ever manufacturing the primary crop of fruit.

There are thousands of different types of olive trees in the world, but to list them all would be impossible. Below are some of the more popular and well known types of olives and olive trees.

Ascolane Olives: Ascolane Olives are fully grown on the olive tree known as the "Ascolana Tenera", which is native to the Marche area of Italy. They are also grown in the country of Jordan as well. The olives are large, with an oil content of sixteen to eighteen percent. When pressed for their oil, they provide a light oil that has various uses. They're conjointly used for green or black table olives. If they are being used for green olives, they're harvested once the flesh is a pale green to yellow color. Once curing in brine, they're meaty and soft with a really gently tart flavor. These olives are ideal for the local specialty of stuffed, fried olives referred to as "Oliva all'Ascolana."

Olive trees require well-drained soil, as they are prone to root rotting. Proper irrigation system is required for olive trees. However, they can withstand extended dry periods. Fertilizers with extra supply of nitrogen can help the growth of olive trees considerably.

As I said previously, it would be near impossible to list all types of olive trees, but the ones listed above are the most common.
