Big bluestem is a distinctive grass that is recognizable by its flowering head that resembles a turkey’s foot – “turkeyfoot” is also one of its other common names. It is one of the main species of the Tallgrass prairie because it loves the heat and moisture, but occurs throughout the prairie grassland areas in southern Manitoba.
