Since Christopher Columbus considered North and South America to be the “New World,” the crops that grew native in those continents are now called “New World crops.” These crops were already being grown before European explorers settled there. Some crops that have grown over many hundreds of years are not actually native, but they were brought over by settlers from other countries.
Some of the grains that were indigenous or native to the Americas included barley, maize, and wild rice. Some of the fruits included blueberries, guavas and prickly pears. Squashes and pumpkins were native to the Americas. Black walnuts, hickories and pecans are native to the Americas. Even though wheat has become a staple crop over the years and many people grow it, wheat is not a native crop to the Americas.
