The orange tree, Citrus sinensis, produces one of the most popular fruits in the world. Where does this tree come from? Southeast Asia, apparently. Oranges slowly worked their way west and were introduced by crusaders to Europe, where they became very popular. As Europeans found the Americas, orange trees were shipped over to many colonies, including Florida.
Today, Brazil is the world's leading producer of oranges (18 million tons) followed by the US (8 million tons), China (6.5 million tons), and India (5 million tons).
