About Mossman River grass
Cenchrus echinatus, commonly known as Spiny Sandbur or Sandspur, is a low-growing annual grass distinguished by its globular, spiny burrs that readily attach to clothing and animal fur. While often considered a weed in agricultural settings, its resilience and adaptability make it intriguing for botanical studies or in native plant gardens where a challenge is sought. Its spiny inflorescences, though problematic, lend it a rustic and distinctive appearance.
Native range
North and South America (tropical and subtropical regions)
Care tips
This species thrives in full sun across a wide range of soils, including poor and sandy ones, making it extremely adaptable and undemanding. Watering should be minimal once established, as it tolerates drought very well; excessive moisture can be detrimental. It requires no fertilization and spreads easily by seeds, so the main care involves controlling its dispersal to prevent it from becoming a nuisance. A common mistake is underestimating its prolific spreading capacity and its ability to rapidly colonize new areas.
