Panicum virgatum ‘Northwind’ (Switch Grass)
Switch Grass 'Northwind', Panicum 'Northwind'Panicum virgatum ‘Northwind’, commonly known as Northwind Switch Grass, is a robust and upright ornamental grass celebrated for its architectural form and adaptability. This warm-season perennial forms dense, narrow clumps of olive-green to blue-green foliage, which maintain their vertical structure throughout the growing season. In late summer, the foliage is topped with airy, golden flower panicles that hover gracefully above the plant, adding texture and movement to the landscape. As autumn progresses, the foliage transitions to a warm golden-yellow before fading to tan-beige in winter, providing year-round visual interest.
Native to North America, Northwind Switch Grass thrives in USDA zones 4–9 and is well-suited to a variety of garden styles, including prairies, meadows, and rain gardens. It grows to a height of 4–6 feet and spreads slowly via rhizomes, making it an excellent choice for borders, screens, or mass plantings. This grass is highly tolerant of diverse soil conditions, including sandy, clay, and wet soils, and it can withstand drought once established. Its seed heads attract birds, enhancing biodiversity in the garden, while its sturdy stems provide winter cover for wildlife.
