Miscanthus floridulus ‘Giganteus’

Giant Silver Grass

USDA Zone: 4-9

Plant number: 8.270.280

(Often listed incorrectly as Miscanthus floridulus) This is a grass of monstrous proportions, forming very tall clumps of green leaves, their tips arching gracefully in layers. Useful as a living screen or hedge, bearing soft-pink plumes in the fall. The corn-like stalks turn creamy tan in winter. Clumps are large, but well behaved and not invasive. Lower leaves have a tendency to wither in late summer, so planting something tall in front is recommended. Plants enjoy moisture, and are even happy growing beside water, however they also tolerate moderate drought conditions. Trim back to the ground in early spring -– power hedge trimmers do a quick job. Excellent for cutting. As an interesting side note, this plant is becoming widely planted as a source of biomass or biofuel.
