- Paspalum quadrifarium is a perennial plant that grows in large, bluish-green bunches, or tufts, reaching 6 ft. (1.8 m) in height.
- Leaves are 5.9-15.7 in. (15-40 cm) long, 0.2-0.3 in. (5-8 mm) wide and glabrous. Leaf sheaths are keeled.
- Flowers are produced in 15-25, 2.4-3.1 in. (6-8 cm) long racemes per plant.
- Paspalum quadrifarium flowers and produces seeds at least twice a year. The small, hard coated seeds range from silver-green to tan in color.
- Ecological Threat
- Paspalum quadrifarium is found in neglected areas along roadsides, streams, wetlands and drains. The plant can spread rapidly through rhizomes or seeds and aggressively forms extremely dense infestations in a few years. Rhizomes move horizontally, sending up suckers, which form large, dense tufts. Native to Uruguay, Paraguay, Brazil and Argentina, this plant is used as an ornamental in Florida and has naturalized in Dade County. It can now be found in Georgia and other disturbed habitats of the southeastern United States. It is considered a noxious weed in Australia.
