Identifying Characteristics

Common carpetgrass is a native, warm-season, stoloniferous perennial grass. The height is can range between 0.5 and 2 feet if unmown. It can be found in lawns as desired or an infestation due to its similarity to other turfgrass species.

Flower Seed Head

The seedhead has 2 to 5 (usually 3) slender racemes 1 to 4 in long.

Where Found

In southern Florida, common carpetgrass stays green all year. Elsewhere, it becomes dormant early in the fall and starts growth in the spring. It produces seedheads and stolons during the active growth period. It reproduces from stolons and from seed. Pure stands are common. It is adapted to clays, sands, mucks, and peats. Most commonly, it is found on slightly acid sandy to sandy loam soils that have a favorable soil-moisture relationship.
