Crops of Mexico

Corn or maize (Zea mays), tomato (Solanum lycopersicum) and cocoa (Theobroma cacao) - the latter used to make chocolate - are the three most important crops introduced from Mexico to the world. All three were domesticated, or brought from wild shrubs and plants into farmable crops, by ancient Mesoamerican civilizations (i.e: living in south-central Mexico), some three millenia ago.
