Orange
Oranges are native to the tropics of Asia, especially the Malay Archipelago. Along with other citrus species they have been cultivated for countless years.
The orange spread to India and the east coast of Africa and then to the eastern Mediterranean. The Roman conquests, the development of Arab trade routes and the expansion of Islam contributed significantly to its spread.
When Christopher Columbus sailed, orange trees were common in the Canary Islands.
Nowadays, they are cultivated in subtropical and tropical America, the northern and eastern Mediterranean, South Africa and Australia.
