Paspalum monostachyum, commonly known as Gulfdune Paspalum, is a perennial grass native to coastal dunes and sandy shores. It is found along the Gulf Coast from Texas to Florida and extends into Mexico. This grass typically grows to a height and width of 0.5 feet (0.2 meters) to 1 foot (0.3 meters), forming dense tufts. It is characterized by its narrow leaves and small, inconspicuous spikelets that appear in the summer. The flowers are not particularly showy, but the grass provides a fine-textured ground cover that is tolerant of salt spray and sandy soils.

Gulfdune Paspalum is valued for its ability to stabilize sandy soils and its use in coastal restoration projects. It is also used in landscaping for erosion control and as a low-maintenance ground cover in areas with poor soil. This grass thrives in full sun and requires minimal water once established, making it suitable for xeriscaping. It prefers well-drained soils and can tolerate drought conditions. While it is not commonly affected by diseases, it can be susceptible to fungal issues in overly moist environments.CC BY-SA 4.0
