Panicum virgatum ‘Heavy Metal’, commonly known as Heavy Metal Switchgrass, is a striking native ornamental grass admired for its metallic blue foliage and upright, columnar habit. Growing 3 to 5 feet tall and 2 to 3 feet wide, this switchgrass cultivar provides vertical structure and fine texture to garden borders, meadows, and naturalized areas.

In late summer, airy, pink-tinged flower panicles rise above the foliage, followed by seed heads that persist through fall and winter, providing food for birds. Its foliage turns golden-yellow in autumn, adding seasonal color and interest. As a native species, Heavy Metal Switchgrass supports pollinators and birds while helping to control erosion and improve soil health.
