Switchgrass (Heavy Metal)
Panicum virgatum · Ornamental grass
Switchgrass (Heavy Metal) is a moderate-growing ornamental grass, hardy in USDA zones 5-9, that matures to about 3–6 ft × 2–3 ft. It does best in full sun and part shade with high water needs in moist, occasionally-dry and occasionally-wet soil. Expect yellow, pink and purple blooms in winter and summer. It attracts small mammals and songbirds, stands up well to black walnut, deer and drought and grows happily in containers.
