Yep one word-MONSANTO! Oh I did my college thesis on GMO and the crap MONSANTO (and a few others) have gotten away with is criminal! Our food supply is dangerously in the hands of greedy corporations. The stuff I dug up took hours and hours of research that most people are too lazy to look for or they just don't know how. I cant wait for my garden to start!!!!
Oh BTW native corns are not going to look or taste the way we are used to them tasting-they are not as sweet and the colors are a lot different. I would grow it if I could!-Desert wont grow corn.
The desert grows lots of types of corn and a lot of other things. What area are you in? Try nativeseeds.org - great seeds for the desert.
