Heavy Metal Switchgrass is a native ornamental grass prized for its stiff upright habit, metallic blue foliage, and airy pink-tinged flower plumes in summer. Its strong vertical form adds movement, texture, and winter interest without taking over the landscape. Tough, low-maintenance, and adaptable, it is excellent for sunny borders, mass plantings, rain gardens, and modern New England landscapes.
