Colombia's cash crop: flowers for Valentine's Day

Nearly three-quarters of flowers sold in the U.S. for Valentine's Day come from Colombia. In the early 1990s, the U.S. government incentivized farmers in Colombia to grow flowers as a way to discourage drug production—and it worked. Today, vast greenhouses, packing warehouses, and industrial fridges are working overtime to ensure roses—the country’s most important flower export—will ship in time.
