Panic Grass

Panicum virgatum (Poaceae) is a clumping, warm-season perennial grass native to North America. It grows 3 to 7 feet tall, forming upright clumps with airy terminal panicles from midsummer onward. Foliage turns gold, orange, red, or bronze in autumn depending on cultivar. It is one of the dominant species of the North American tallgrass prairie.

Switchgrass thrives in full sun across a broad range of soils and moisture conditions, from dry uplands to seasonally wet sites. It tolerates clay, drought, and poor soils. No significant pest or disease problems are documented. The species is important for erosion control, biofuel research, and wildlife habitat. Hardy in Zones 5a to 9b.
