Panicum virgatum ‘Heavy Metal’ is a popular cultivar of native switchgrass known for its intense steel-blue leaves that form a dense, upright clump reaching 3 to 4 feet tall and wide. This compact grass adds year-round architectural interest and vibrant color, especially when paired with warm-season blooms or fall foliage. Heavy Metal thrives in full sun and adapts well to a variety of soils, exhibiting good drought tolerance and low maintenance needs. It’s excellent for borders, naturalistic plantings, and prairie-style gardens.
