Switchgrass
Panicum virgatum
📖 About this plant
A tall, upright, native North American prairie grass that has become one of the most popular ornamental grasses for landscaping. It forms sturdy, vertical clumps of blue-green to green leaves that turn golden-yellow to red in autumn. Airy cloud-like flower panicles appear in midsummer and persist through winter, providing year-round interest. Extremely tough, low-maintenance, and ecologically valuable for pollinators and birds.
