Botany
Classification and Distribution
Olea europaea L. belongs to the family Oleaceae and is the only olive species with significant commercial cultivation. Its native range spans the Mediterranean Basin from the Iberian Peninsula east to the Levant, with naturalised populations now extending into parts of Central Europe, including southern Germany, where Mediterranean climates are locally reproduced in sheltered valley locations.
The species is divided into two primary subspecies: O. europaea subsp. europaea (the cultivated olive) and subsp. cuspidata, found across sub-Saharan Africa and the Indian subcontinent. Within cultivated olives, over 1,000 named cultivars are documented, varying substantially in fruit size, oil content, and environmental tolerance.
