Sirop d'érable. Jardiner avec ses élèves en classe, dans la cour, c'est possible ! The Citrus Family Tree. All the oranges, lemons, limes, and grapefruits you’ve ever eaten are descendants from just a few ancient species. A version of this story appears in the February 2017 issue of National Geographic magazine. Citrus, in many ways, stands alone. So many cultivated species have come from so few primary ancestors.
Just three, in fact: citrons, pomelos, and mandarins, all native to South and East Asia before they started their journeys west, to places like Florida, California, and Brazil that built entire economies around fruits from the other side of the world. Such simple lineage is the result of impressive commonality. Almost all citrus has the rare genetic combination of being sexually compatible and highly prone to mutation. Such traits allow their genes to mix, for thousands of years on their own, and eventually, at the hands of humans. No other fruit genus can boast such pedigree, and new research is bringing clarity to the origin of citrus.
