The orange blossom (Citrus sinensis) was designated as the state flower of Florida in 1909. The blossom of the orange tree is one of the most fragrant flowers in Florida. Millions of white flowers from orange trees perfume the air in central and southern Florida during orange blossom time. Florida also recognizes the orange as official state fruit and orange juice as the state beverage.

Citrus fruit, especially oranges, are a major part of Florida's economy. Florida produces the majority of citrus fruit grown in the United States (in 2006, 67 percent of all citrus, 74 percent of oranges, 58 percent of tangerines, and 54 percent of grapefruit). About 95 percent of commercial orange production in the state is processed (mostly as orange juice).
