Olive Tree

The olive tree (Olea europaea) is an evergreen tree of the Oleaceae family, native to the Mediterranean region and neighboring parts of western Asia. It is well adapted to hot, dry summers and mild, relatively wet winters. Its narrow, leathery leaves have a gray-green upper surface and a silvery underside covered with tiny hairs that help limit water loss.

Small, pale flowers appear in clusters in spring and are mainly pollinated by wind. The fruit, known as the olive, is a drupe containing a single seed surrounded by fleshy tissue. Olives change color as they mature, usually from green to shades of purple or black, although color alone does not always indicate the exact stage of ripeness. Olive cultivation has a very long history in Mediterranean societies.

The fruit is eaten after processing because fresh olives are naturally bitter due mainly to compounds such as oleuropein. They may be cured in brine, water, salt, or other traditional preparations. Olive oil is obtained by crushing the fruit and separating the oil from the solid and watery parts. Its composition varies with the variety, growing conditions, and processing method.

Olive trees also provide habitats and resources for many organisms in agricultural landscapes. Their wood can be used for small objects and furniture, while pruned branches and other plant material may be used as fuel. Because the tree can tolerate drought and live for a long time, it has become closely associated with Mediterranean agriculture and culture.
