Synonym(s): torpedo grass, couch panicum, wainaku grass, creeping panic

Torpedograss is a perennial grass that can reach up to 3 ft. (1 m) tall. Plants have long, creeping rhizomes with sharp-pointed (torpedo-like) tips. Leaves are linear, flat or folded, 10 in. (26 cm) long, 0.3 in. (5.3 mm) wide with a whitish, waxy covering. Leaf sheaths can be glabrous or hairy and the ligule is membranous with short hairs. Flowering occurs nearly year round. Flowers develop in branched, open inflorescences that are 2.8-7.1 in. (7-18 cm) long. Torpedograss is native to Africa and Eurasia and was introduced into the United States around 1876. This species can occur in a wide variety of habitats. Plants are usually found in damp soils of riparian zones, but can also be found in pastures and on sand dunes. Plants are salt-tolerant.
