Little Bluestem (Schizachyrium scoparium) is an interesting prairie grass. At only 3 feet tall, it's much shorter than Indian Grass, Big Bluestem or Switch grass. In Fall, clumps of Little Bluestem can be striking, as the fluffy seedheads catch the light, drawing your eye to the orange-colored stems.
