The Olea europaea, better known as the olive tree, is a tree from the olive family that originates from the eastern Mediterranean region. This ancient tree species is often associated with peace and prosperity, as well as wisdom and hope, in historical texts. The olive tree was already cultivated during the Bronze Age and further spread throughout the Mediterranean region, where the climate is ideal for the growth of this tree.
The evergreen Olea europaea is a long-term plant that can grow up to twelve metres high. It has a gnarled trunk, leathery leaves and produces small, fragrant flowers followed by edible fruits, the olives. The fruits vary from green to black, depending on ripeness. The tree has a long lifespan, with some specimens being thousands of years old.
Olive trees require a sunny location and well-draining soil. They can tolerate extremely dry conditions and have a low nutritional requirement. In addition to some protection against frost, the care is relatively easy: the tree only requires occasional pruning to maintain the shape and stimulate the production of fruits. Watering is usually only necessary during dry periods and unnecessary shoots can be regularly removed.
