'Shenandoah' Switch Grass (Panicum virgatum 'Shenandoah') is most notable for its foliage coloration. Starting out green, the leaves turn increasingly red throughout the summer, eventually resembling Bloodgrass, and become burgundy in fall. The flowers have a reddish tint as well. It grows upright and slowly to a height of 4 feet, likes full sun and dry to moist soils, and makes an especially appealing specimen plant in the landscape..
