Carpetgrass (Axonopus affinis) is a creeping, stoloniferous, perennial warm season grass. It is characterized by flat, two-edged runners or stolons; by wide leaves with blunt, rounded tips and by long, slender seedstalks that terminate with two branches, very similar to crabgrass. Stolons are flat, widely branched and root at each node.
From the sandy soils of East Texas to Florida and north to Virginia, Alabama and Arkansas, carpetgrass is found in fields, woods, along roadsides, pastures and lawns.
Also known as flatgrass, Louisianagrass and as "petit gazon" by the Creoles of Louisiana, carpetgrass is native to the Gulf Coast states and other tropical climates. It is a creeping, perennial grass that can be recognized by the blunt rounded tips of its leaves, flat stolons and a tall seedstalk with two branches at the apex. It forms a dense mat and will crowd out most other species.
