paspalum

Paspalum is a genus of grasses in the family Poaceae. It comprises a diverse group of species native to warm regions of the world, especially the Americas, but now widespread in tropical and subtropical climates. Members of the genus are used as forage grasses, turfgrasses, and, in the case of Paspalum scrobiculatum, as a cereal grain.

Description: Paspalum species are typically warm-season grasses. Many are rhizomatous or stoloniferous, forming dense stands. Leaves are generally slender, with inflorescences consisting of branched panicles bearing small spikelets.

Notable species and uses: Seashore paspalum (Paspalum vaginatum) is highly salt-tolerant and is widely planted for turf on coastal lawns and golf courses. Bahia grass (Paspalum notatum) is used for pastures and lawns in warm regions. Dallisgrass (Paspalum dilatatum) is common for forage and has become naturalized in many areas. Kodo millet (Paspalum scrobiculatum) is cultivated as a grain in parts of Asia. Tall paspalum (Paspalum urvillei) is also used for forage but can be invasive outside its native range.

Ecology and management: Many Paspalum species tolerate heat and drought, with varying tolerance to salinity. Establishment is usually by seed; turf applications require proper irrigation and mowing regimes, while forage grasses are managed for grazing and hay. Some species can behave as weeds or invasive when introduced outside their native ranges.
