Citrus medica
Citron
The oldest of the cultivated citrus and one of the three species from which the rest were bred, Citrus medica makes a small thorny tree of 2 to 4.5 metres with large leathery aromatic leaves. The fruit is enormous, knobbly and almost all rind, with very little flesh or juice.
It is planted for the fruit, the fragrance and the cultural weight rather than for the crop. Fruit is used candied and for its rind, and the etrog selection has been grown for ritual use for well over two thousand years.
