Notes: Couch grass is a low-growing perennial with grey-green leaves and runners which root readily. It spreads rapidly by seed and runners and even small fragments will root if dumped with garden refuse.

It is regarded as an Australian native and is widely planted as a lawn grass. It occurs in all states and territories. It invades wetlands and river edges in southern Western Australia.
