Cenchrus spinifex, commonly known as beach spinifex, is a perennial grass native to coastal regions of Australia and other tropical areas. It typically grows in sandy soils and is characterized by its long, slender leaves and spiky seed heads. This grass plays a crucial role in stabilizing sand dunes, preventing erosion, and providing habitat for various wildlife. The plant can reach heights of up to 1 meter and thrives in full sunlight. Its extensive root system helps it adapt to harsh coastal conditions, making it an important species for maintaining healthy coastal ecosystems. Cenchrus spinifex is also used in landscaping and erosion control projects.
