what do olives grow on

Olives grow on olive trees, which are evergreen plants that can grow as shrubs, hedges, or trees. The olives fruit, also called an "olive", is of major agricultural importance in the Mediterranean region as the source of olive oil. Olives bear small pitted fruits that can be cured for table consumption or pressed for oil. Olives grow best in full sun in regions with Mediterranean-type climates, long, hot, dry summers with some winter cold. They grow well in a wide range of soils, from sandy to loam to clay, but the soil must be well-drained. Olives are generally shallow-rooted plants.
