Citrus junos

Yuzu is a citrus fruit in the citrus or Rutaceae family, native to Japan, Korea and China. It forms an upright shrub or small tree, which commonly has many large thorns.

• Leaves are notable for a large petiole, resembling those of the related kaffir lime and ichang papeda, and are heavily scented.
• Fruit looks somewhat like a small grapefruit with an uneven skin, and can be either yellow or green depending on the degree of ripeness.
• Yuzu fruit, which is very aromatic, typically is between 5.5 and 7.5 cm in diameter, but can be up to 10 cm or larger, as large as a regular grapefruit. A variety in Japan called lion yuzu or shishi yuzu is especially large and has knobby skin.
