Torpedograss

Panicum repens

Description


Non-Native

Torpedograss is a perennial grass native to Australia. It can form dense colonies from extensive, creeping rhizomes in shallow water or moist soils and can grow to 3 feet in height. Leaves are flat or folded, up to 5 inches long and about 1/2 inch wide or less. Flowers at the tips of the stems, on open branches up to 5 inches long.

Submerged portions of all aquatic plants provide habitats for many micro and macro invertebrates. These invertebrates in turn are used as food by fish and other wildlife species (e.g. amphibians, reptiles, ducks, etc.). After aquatic plants die, their decomposition by bacteria and fungi provides food (called “detritus”) for many aquatic invertebrates. Torpedograss is grazed by muskrats, nutria, rabbits, and other rodents but since it is non-native it should not be spread.

This plant is not native to North America and it is illegal to possess or transport this species in Texas. Please report any sightings of this plant to Texas Park and Wildlife Department.
