Citrus x paradisi, commonly called grapefruit, is a tree that grows to be about 30 to 50 feet tall. It produces large fruit with a dark orange peel and a bright pinkish-red inside. The fruit can be sweet, bitter, or sour. An essential oil can be made from the skin. Oil can be collected from the seed as well.
