Starr 090121-1001 Axonopus fissifolius

Axonopus fissifolius, commonly known as the carpetgrass, is a species of perennial grass native to the tropical and subtropical regions of the Americas. It is widely used in landscaping and as a turf grass due to its dense growth and tolerance to various soil types and environmental conditions. This article provides an overview of Axonopus fissifolius, including its characteristics, habitat, uses, and cultivation.

Characteristics

Axonopus fissifolius is characterized by its mat-forming habit, making it an excellent ground cover. The grass has broad, flat leaves that are a vibrant green color. It typically grows to a height of 15 to 30 cm (6 to 12 inches), with the leaves ranging from 3 to 5 cm (1.2 to 2 inches) in width. The plant produces small, inconspicuous flowers during the summer months, which are followed by seed production.

Habitat

Originally from the Americas, Axonopus fissifolius has adapted to a wide range of climates and can be found in areas from the southern United States to Argentina. It prefers moist, fertile soils but can tolerate a variety of soil types, including those that are sandy or clayey. Axonopus fissifolius is commonly found in open grasslands, roadsides, and disturbed areas, as well as in managed landscapes and lawns.

Uses

Due to its dense growth and ability to form a thick carpet, Axonopus fissifolius is primarily used for turf in lawns, parks, and golf courses. It is especially valued in regions with tropical and subtropical climates where its growth is optimized. Additionally, its erosion control properties make it useful for stabilizing soil in areas prone to erosion. In some regions, Axonopus fissifolius is also used for forage, providing a source of feed for livestock.

Cultivation

Cultivating Axonopus fissifolius involves planting seeds or sod in a well-prepared soil bed. The grass prefers full sun to partial shade and requires regular watering, especially during the establishment phase. Once established, Axonopus fissifolius is relatively low maintenance, requiring only occasional mowing to keep it at the desired height. Fertilization can help maintain its dense growth and vibrant color, but excessive use of fertilizers should be avoided to prevent nutrient runoff and environmental damage.

Environmental Impact

While Axonopus fissifolius is beneficial for erosion control and as a turf grass, it can become invasive in some areas, outcompeting native vegetation and altering natural habitats. Management practices should be implemented to control its spread in sensitive areas.
