The word granatum literally means "seed-bearer," referring to the many seeds contained within the fruit. This nomenclature reflects both the geographical origin and the main characteristic of the fruit.
Geographic origin
Punica granatum is native to the region from Iran to the Himalayas, including northwest India. This original range corresponds to areas with a Mediterranean or semi-arid climate, adapted to hot summers and mild winters. The plant has thrived in these regions thanks to its drought resistance and its ability to adapt to varied soils.
History of its diffusion
Pomegranate cultivation quickly spread throughout the Middle East and the Mediterranean through trade and human migration. The Phoenicians and Romans played a central role in its spread, introducing the plant to Europe and North Africa.
