Heavy Metal Switch Grass

Panicum virgatum 'Heavy Metal'

Plant Details:

Plant Type: Ornamental Grass
Plant Family: Poaceae
Plant Description: Clump-forming, warm season, ornamental grass. Long, slender, metallic-blue leaves form a dense columnar clump but may flop in overly fertile soils or too much shade. Fine textured, pink-tinged seed heads appear in fall and provide excellent winter interest if left uncut. May reseed. The species is native from Utah to the east coast.

Maintenance:

Maintenance Type: Ornamental Grass - Medium
Plant Care: Ornamental Grass - Medium (showy non-turf grasses that go dormant in winter, 3-6' tall): Use hand pruners or hedger to cut and remove 2/3 of the total grass height. Trim edges. For warm season grasses (more common), this is best done in late winter to early spring. For cool season grasses apply the same maintenance practices in the late fall, once the plant is dormant.
