Citrus junos (Yuzu Lemon)

Yuzu (Citrus × junos, from Japanese 柚子 or ユズ) has been cultivated mainly in East Asia, though it has also recently been grown in New Zealand, Australia, Spain, Italy, and France. It is believed to have originated in central China as an F1 hybrid of the mangshanyeju subspecies of mandarin orange and the ichang papeda.

This fruit resembles a yellow clementine with uneven skin and can be either yellow or green depending on the degree of ripeness. Yuzu fruits, which are very aromatic, typically 5.5-7.5cm across but can be as large as a regular grapefruit (up to 10cm, or larger).

Yuzu forms an upright shrub or small tree 4m high, which commonly has many large thorns. Leaves are notable for a large, leaf-like petiole, resembling those of the related makrut lime and ichang papeda, and are heavily scented.
