Some people may think of “The Jungle Room” at Graceland, where Elvis Presley lived when they hear the term “carpet grass.” This is not something new, but it is also not something a person can put down on the floor in their home.

Carpet grass is for outdoor use only (unless you’re adventurous and feel like mowing a grass carpet) and is real grass that grows and needs to be tended to like any lawn, only with slightly lower maintenance. It gets its name because it is laid out like a carpet over the ground, and the grass looks like a carpet when it is appropriately kept up!

What is Carpet Grass?

Carpet grass is a member of the genus axonopus, which is part of the grass family. This a natural grass type that is heard of under many names, including broadleaf carpet grass, bermudagrass, flatgrass, Louisianagrass, or as petit gazon (which translates to “little grass”) as spoken by the Creole community of Louisiana. One of the best known carpet grass species is axonopus affinis.

Carpet grass is a perennial plant, with coarse leaves and a creeping growth habit. This type of growth habit creates a dense turf-like appearance. It can be grown both from grass seed and it is a rhizomatous plant — this means that once it is established, it will spread like wild fire.

Root System

Carpet grass grows from very shallow roots. This means that the plant does not have very good drought tolerance. In order for a plant be able to handle drought stress, the roots must be able to reach levels of the soil that do not dry out as quickly.

Leaf Blades 

You can recognize carpet grass by its blunt, rounded tip leaf, its flat stolon, and wiry stems with branching at the apex. Leaf blades are a deep green color. This type of leaf growth pattern is known as tall fescue growth.

Growth Pattern 

Carpet grass has a dense turf like appearance. Each blade of grass grows a seed head which catches on quickly and spreads far and wide. Carpet grass has a weedy appearance, especially if it is allowed to grow, but it fills all the spots of dead grass or areas where the grass is not growing.
