PAMPAS GRASS

Pampas grass (Cortaderia species) is a very tall, clumpy grass with fluffy flower heads. It competes with native vegetation and is a fire hazard. Pampas grass is a perennial grass that grows in clumps up to 1.5 m wide.

Once established, pampas grass is highly competitive, restricting the regeneration of native trees (Government of South Australia 2021), and can crowd out native plants, competing for light, water, nutrients and space (Parsons & Cuthbertson 1992).

Pampas Grass occurs in moist areas mostly around cities and towns, mainly in temperate parts and in south-east Queensland and in some drier semi-arid areas, normally near waterways (AVH 2021). Cortaderia selloana subsp. jubata occurs mainly in Tasmania and Victoria, while Cortaderia selloana subsp.
