Carpetgrass

(Updated: August 22, 2022)

Description

Carpetgrass (Axonopus) is a slow-growing, medium-green (and sometimes greenish yellow), coarsely textured turfgrass that is adapted to low-maintenance, general-purpose turf. It prefers full sun to moderate shade and performs well in wet, shady, acidic soils where other grasses may not. Carpetgrass looks very similar to centipedegrass except that it produces a crabgrass-like seedhead, and centipedegrass has hairs along the edges of the leaves.
