The olive tree (Olea europaea) is an evergreen native to the Mediterranean, prized for its silvery green leaves and rustic fruit. It thrives in full sun with good air circulation and well-drained soil. Drought-tolerant, but avoid overwatering to prevent root rot. Suitable for pots, it can be pruned for shape and indoor display. Hardy down to around −5°C (23°F), but benefits from frost protection in colder areas.
