  Erscheinungsbild

  Very long-lived evergreen tree, one of the oldest plants to be cultivated as a source of oil in the Mediterranean regions. The trees growing in olive groves are pruned. The more gnarled a tree is, the greater its yield reputedly becomes. Olive trees reach great age. The oldest tree stands in Trevi, Italy, and is around 1700 years old.
