What is a cogon grass?

Cogon grass (Imperata cylindrica) is a perennial grass native to tropical and subtropical regions, known for its invasive nature and ability to thrive in various environments. It features long, narrow leaves and fluffy, white flower heads that can produce large quantities of seeds, allowing it to spread rapidly. This grass can outcompete native vegetation and is often considered a problematic weed in agricultural and natural ecosystems. Management of cogon grass is challenging due to its resilience and adaptability.
