The History of Zucchini:

Zucchini has beginning roots in Mesoamerica (central Mexico through Belize, Guatemala, El Salvador, Honduras, Nicaragua and Costa Rica. Although it was native to North and South America, it was introduced to the Old World after Columbus’ explorations in 1492.

The zucchini we know today was developed in Italy in the later half of the 1800’s. It was likely re-introduced to America by Italian immigrants in the 1920’s.
