Bush Beans were “invented” by man, when he first decided to grow food because his big feet hurt from waking the Earth. Sound familiar? We haven’t changed that much in 100,000 years. We invented a few new varieties of beans, went to the moon and back, shop at the local WallMart and still our big feet hurt. So hybridizing a few plants more than a few hundred years ago didn’t help my feet much, but I do enjoy the Purple Bush Bean.
