Orange is one of the most widely-planted and prolific citruses grown in Hawaii. The taxonomy of Citrus genus is complex, and cultivation goes back at least 2500 years. While the precise number of species is unclear, all originated from three primary ancestors: citron, pomelo and mandarin.
The orange is a hybrid between pomelo and mandarin. There are sweet and bitter oranges and sweet oranges can be further divided into three groups: navel, common, and blood oranges.
Oranges are rich in vitamins and minerals, especially vitamin C. Similar to all citrus, the peel contains aromatic oils and the fruit’s zest is used to add flavor to cakes and salad dressings.
The flesh is juicy, aromatic, acidic, and refreshing with a balance of sweet and sour.
