The Orange, specifically, the Sweet Orange, is a hybrid, between pomelo and mandarin. Sweet Oranges were mentioned in Chinese literature as far back as 314 BC, but is unknown in the wild state. Oranges were considered a luxury item and wealthy people grew them in private conservatories, called orangeries.

By 1646, the Sweet Orange was well known throughout Europe. Spanish travellers introduced the Sweet Orange to the American continent. On his second voyage in 1493, Christopher Columbus may have planted the fruit in Hispaniola. Like most citrus plants, Oranges do well in moderate temperatures and require considerable amounts of sunshine and water. They are sensitive to frost so should be protected during the winter months.

Orange trees are the most cultivated fruit tree in the world and account for approximately 70% of citrus production. They are widely grown in tropical and subtropical climates for their sweet fruit. The fruit of the Orange tree can be eaten fresh, or processed for its juice or fragrant peel. In 2013, 71.4 million metric tons of Oranges were grown worldwide, production being highest in Brazil and the American states of Florida and California.
