Switchgrass
Panicum virgatumAlso known as Panic Grass, Tall Panic Grass, Blackbent, Wobsqua Grass
Switchgrass anchors the North American tallgrass prairie with an expansive network of fibrous roots that can plunge more than three meters deep into rich prairie soils. Its upright culms burst into airy, cloud-like panicles of purplish florets each summer, swaying vigorously in grassland breezes. In autumn, the foliage transitions to radiant golden-orange hues that persist through winter, providing crucial structural cover and seed for ground-foraging wildlife.
