Switchgrass
Panicum virgatum
outdoorA warm-season native North American grass with fine-textured, upright foliage that transitions from green to striking reds, oranges, and purples in autumn. It produces delicate, airy flower panicles on tall stems that persist through winter, providing excellent late-season interest and wildlife value. Highly adaptable, drought-tolerant once established, and invaluable for prairie gardens and naturalized landscapes.
