This doesn’t have much to do with cold climate gardening, but I found this article fascinating. Apparently Nepalese farmers have been growing the same corn as native Americans for so long they think it’s native to Nepal–but it’s not. How did it get there? No one is really sure, but that fact remains that “in Nepal today, maize is grown on more than 800,000 hectares comprising 30% of the total cultivated land and remains the staple food of populations in the hill regions.”
