Citrus Fruits Trivia Quiz – The Citrus Family Tree

Citrus fruits originated in Southeast Asia and the foothills of the Himalayas and spread around the world along trade routes. Most modern citrus fruits are hybrids of a few ancestral species, such as pomelos, mandarins and citrons.

The sweet orange comes from pomelo and mandarin ancestors, and the navel orange began as a mutation in Brazil. Bitter Seville oranges make marmalade, blood oranges get their color from anthocyanins and Japan prizes aromatic yuzu.

Citrus has saved lives. In 1747, James Lind showed that citrus could prevent scurvy, and British sailors were later called limeys. Grapefruit, however, can interfere with some medicines, so doctors advise caution.
