Olea europaea is an evergreen fruit tree or shrub native to the Mediterranean, Asia and Africa. It is an important commercial tree used for fruits for eating and for the production of olive oil. The tree matures to have a gnarled and twisted trunk and grows to 20-30 feet tall. It can be grown outdoors in zones 8-10 or brought indoors or in a greenhouse in colder areas. It requires 2 months of temperatures in the 40-50 degree F range to flower. The white fragrant flowers occur in 2 inch long panicles in summer and are followed by a green drupe (the olive) that matures to purple. They can be harvested at either stage.
