Cenchrus longispinus, commonly known as long-spined sandbur, is a perennial grass native to the Americas. It typically grows in sandy or disturbed soils and is characterized by its long, spiny seed heads that can be quite sharp. This grass is often found in open fields, roadsides, and coastal areas. The plant can reach heights of up to 1 meter and has a clumping growth habit. Cenchrus longispinus is known for its ability to thrive in dry conditions, making it a resilient species. However, its spiny seeds can be a nuisance, as they tend to cling to clothing and animal fur.
