Dallas grass

Paspalum dilatatum

''Paspalum dilatatum'' is a species of grass known by the common name dallisgrass, Dallas grass, or sticky heads. It is native to Brazil and Argentina, but it is known throughout the world as an introduced species and at times a common weed. Its rapid growth and spreading rhizomes make it an invasive pest in some areas. It is present in the southern half of North America, southern Europe, much of Africa, Australia, New Zealand, and many tropical and subtropical areas.

''Paspalum dilatatum'' is a food source for several avian species, including the long-tailed widowbird.

The common name dallisgrass was derived from T. A. Dallis, a 19th-century farmer who grew the species extensively near La Grange, Georgia.
