Switchgrass Seeds – Panicum Virgatum, Native Prairie Ornamental Grass
Switchgrass (Panicum virgatum) is one of North America's most celebrated native prairie grasses — and for good reason. This tall, clumping perennial is remarkably tough, thriving in poor soils, drought, flooding, and low-fertility conditions where other plants struggle. It's a powerhouse of ecological value and ornamental beauty in one package.
In summer, feathery seed heads (panicles) sway gracefully above the foliage. Come fall, the entire plant transforms into a stunning golden yellow display that holds its form beautifully through winter — making it a favorite for fresh and dried arrangements alike.
