Fountain Grass
Pennisetum setaceum
Tufted, erect perennial grass to 1 m tall in dense multi-stemmed tussocks. Leaves to 40 cm long by 0.3 cm wide, rough to touch. Flower heads in a purplish, cylindrical spike 8-15 cm by 3-4 cm, January and April to June.
Threat / Problem
• Invades disturbed areas and competes with native species.
Spread
• Rhizome fragments can generate new plants. Germination from seed is slow. Spread by water, wind, contaminated soil or dumped garden waste.
Control
• Spot spray, best in late Spring to Autumn, as an immature plant before rhizome growth and flowering.
