Torpedo Grass
weed identification
Torpedo grass is a tall grass with tough stems which can reach up to one metre tall. The stems are green, flat and sometimes have flowers. The leaves sometimes have a white and waxy covering on the underside. The emergent plant has creeping underground stems (rhizomes).The grass can form extensive dominant mats. Torpedo grass can tolerate saline conditions.
It prefers warm environments, wet habitats and commonly grows in sandy soils. It is tolerant to drought and temporarily flooded conditions.
Primarily by underground stem fragments (rhizomes), viable seeds are rarely produced.
Underground stems fragments (rhizomes) are dispersed by water, animals and vehicles.
Torpedo grass can be used for erosion control and provide bank stabilisation.

Disadvantages of Torpedo Grass
Torpedo grass can grow quickly and if the infestation is too dense it can have negative impacts on the water body.
- Potential to dominant water bodies and displace other native water plants
- Prevents regeneration of more desirable plants
- Reduces critical food and habitat for fish and other aquatic animals
- Potential to obstruct water flow and block pumps
- Restrict water-based recreational activities
