Hm, this is interesting: a perennial cover crop producing an edible grain.
Scientists with Agriculture and Agri-Food Canada and Dalhousie University have trialed Kernza in the Maritimes for the first time. Unlike wheat or barley, the perennial grain grows back each year, meaning farmers don’t have to start from seed every spring. Researchers say that could lower expenses associated with planting crops, including seed, fertilizer and fuel.
...Mills said wheat can cost anywhere from $500 to $800 per acre to grow. By comparison, he estimates Kernza at closer to $100 per acre. It can also do double duty, producing both grain and forage for livestock in the same growing season.
...It is already being used by artisan bakeries to make bread and by breweries to make beer, though it remains a niche product.
