Citron

Citrus medica

Citrus apple, Wild lemon, Yellow citron, Etrog (Eng.), Sitroen (Afr.)

1/3

This ancient citrus is distinguished by its fragrant fruit, leaves and flowers. It bears fruit that few are familiar with, as it is seldom seen or used in its natural unprocessed form. With its trailing branches, its lemon-scented green leaves, its clustered flowers and its large, yellow egg-shaped fruits the Citron plant has been an important attribution to the culinary and medicinal applications ​and is even considered as ornamental - grown as patio plants or even Bonsai.
