The true olive (Olea europaea) is the source of the fruit also called olive and of olive oil; it is the most commercially important member of the family. The olive tree, a small evergreen, has been cultivated since the beginning of historical times in its native Asia Minor. Its cultivation spread very early to all the Mediterranean countries, and this is still the chief area of production. It is now grown also in Australia, S Africa, Mexico, and California, where it was introduced (c.1769) at the San Diego mission by Spanish missionaries. The mission olive of today, a variety raised both for the table and oil, was developed from trees grown at California's missions.

The several hundred horticultural varieties of olives, many cultivated since ancient times, differ in appearance, flavor, and oil content. Some varieties have been developed especially for oil extraction, the chief use of the fruit. Of the eating olives, green olives are picked when full-grown but unripe, and are often pitted and stuffed with pimientos or anchovies. Ripe olives, usually purplish black, are richer in oil. Both green and ripe olives are treated with lye to remove the bitter quality and then packed in brine. Olive wood, hard and close-grained, is used for cabinetwork and furniture. Olive trees are subject to several diseases; the bacterium Xylella fastidiosa, found in Europe for the first time in 2013, has devastated infected groves.

According to Greek mythology the olive was Athena's gift to mankind, and Athens was named in her honor for this gift. The olive branch has been the symbol of peace since before Christian times, because the oil could be used both to heal human ills and to calm troubled waters. The first vegetation seen by Noah after the Deluge was the branch of olive brought back by the dove, and a dove bearing an olive branch has also been used in art as a symbol of peace.

Olives are classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).

You can't eat most olives straight off the tree, they contain a glycoside called oleuropein, which makes them intensely bitter. They need to be cured before they are edible. Most commercial olives are cured in Lye- (sodium hydroxide)-one of the main ingredients of Drano. Canned black olives have been pasteurized and soaked in ferrous gluconate – avoid them. The curing process is very tedious and takes up to 3 months. They need to be in water the whole time. The first month, the water needs to be replaces daily. Then salt water is added for the next month or two.
