Giant Parramatta grass (Sporobolus fertilis syn Sporobolus indicus var. major ) is declared noxious in the Illawarra District Weeds Authority control area (including Kiama, Shellharbour and Wollongong council areas).
The weed control class is 3. This means that:
“The weed must be fully and continuously suppressed and destroyed”.
Description: A coarse tussocky grass up to 2m. The seedhead, which resembles a rat’s tail, can grow up to 40cm long. Branches at the bottom of the seedhead droop away from the central stem when fully laiden with seed. The seeds are white in colour initially, turning yellow-brown at maturity. The plant can grow to 40cm in diameter, forming thick swards, which hay off in winter leaving a distinctive straw of seedless heads. Native to Southern Africa.
Problem: A very aggressive plant that spreads rapidly. Low nutritive value and unpalatable. Devalues farms. Despite all intentions to control it, it is anticipated that the plant will reach its ecological limit, rather than be controlled. Current measures may delay it reaching this limit by several years.
