dallis grass

Dallis grass, scientifically known as Paspalum dilatatum, is a tall, tufted perennial grass native to South America. It belongs to the large genus Paspalum, which includes many annual and perennial grasses found in warm regions worldwide.12

Dallis grass was introduced to the southern United States as a pasture and forage grass. While some Paspalum species are valuable forage, others, including certain varieties of dallis grass, can be considered invasive outside their native ranges. These grasses typically have flat, linear leaves and utilize a C4 photosynthetic pathway, which enhances their drought tolerance.12
