Torpedo grass (Panicum repens)
N/A
About this plant
Panicum repens, commonly called torpedo grass, is a fast-spreading perennial grass known for its long, pointed underground stems (rhizomes) that help it spread quickly. It is often used for erosion control but can become invasive in some areas. The grass has narrow leaves and produces small flowers on tall stalks during its blooming season.

Allergy information
Panicum repens, also known as torpedo grass, can produce pollen that might cause mild allergic reactions in sensitive individuals, such as sneezing or itchy eyes. To reduce exposure, avoid areas where this grass is flowering heavily during its blooming season.
Common problems
If overwatered or planted in very wet soils, it may become invasive and crowd out other plants. It can also spread rapidly through underground runners, making it hard to control.
Uses
Used mainly for ground cover and erosion control in warm climates. It is not commonly used as an ornamental plant due to its invasive nature.
Notes
Because of its aggressive spreading habit, regular pruning or containment measures are recommended to prevent it from overtaking other plants or areas. It is not typically grown indoors.
