Olive trees are cultivated largely for their edible fruit, although other olive species are grown for their foliage and wood. This species produces minute white flowers with an immature green, edible fruit that turns bluish or purplish when ripe.
Both the immature and ripe fruit of the olive tree can be quite acidic and must be properly prepared for human consumption. Oil is extracted from the fruit and used for cooking and other purposes.
