Panicum miliaceum is native to Asia, where it has been cultivated for thousands of years. In the Flora region, it is grown for bird seed and is occasionally planted for game birds. It is also found in corn fields and along roadsides. In Asia, P. miliaceum is still grown for fodder and as a cereal, its fast germination and short growth period enabling it to be sown following a spring crop. It also has one of the lowest water requirements of any cereal grain.
