Seville

The most famous of the unimproved (bitter) oranges, this historic orange of ancient and European courtyards is widely used as a decorative plant in Europe as well as in the United States, especially in the Southwest. It has thorny branches with long, dark green leaves that taper into a point. Besides being used for marmalades and certain liqueurs, including Curaçao and Grand Marnier, this very sour fruit’s peel is popular for making into candied orange peel.
