Paspalum denticulatum, commonly known as Toothed Paspalum, is a perennial grass that is deciduous in cooler climates and evergreen in warmer regions. It is native to tropical and subtropical areas of the Americas, including riverbanks, wet meadows, and other moist, open habitats. This species typically grows to a height of 1-3 feet (0.3-0.9 meters) and is characterized by its narrow leaves and toothed sheaths, which give the plant its common name. The inflorescence is a raceme, with small, inconspicuous flowers that may be present throughout the growing season in its native range.

Toothed Paspalum is valued for its ability to thrive in wet conditions and is often used for erosion control along waterways. It is also utilized in wetland restoration projects and as a forage grass in pastures. In garden settings, it can serve as a ground cover in damp areas. It requires full sun to part shade and prefers medium to slow-draining clay or loam soils, with consistent moisture. While it is not typically grown for its ornamental qualities, its dense growth habit can be beneficial in landscape design. Care should be taken as it can become invasive in some regions outside its native range, particularly in wetland areas.CC BY-SA 4.0
