You can find the parent species of this plant throughout the United States. It is indigenous to savannas, rocky bluffs, forested woods, and prairies. The Heavy Metal was introduced in the 1980s, and it is known for its columnar habit and metallic bluish foliage. This switch grass has a narrow upright habit that produces upright clumps.
The Heavy Metal switch grass is also called the blue switch grass. This species has a striking blue leaf color that lasts throughout the year. The erect growth habit is stable and will not fall over during those heavy rains. While the steel blue foliage dazzles your yard, pinkish flower panicles extend above the foliage in the late summer. The foliage transforms into a golden color by autumn. For winter, the leaves develop into a golden brown tone. The Heavy Metal seed heads stay around throughout the winter, and they provide your landscape with some added interest. You can expect this switch grass to grow about 3 feet tall and 2 feet in width. The blooms rise about 5 inches above the foliage.
This switch grass takes your landscape to the next level. When the sun hits the flowers, the light bounces off the plant. You can use the Heavy Metal switch grass throughout your landscape.
