Sporobolus robustus, commonly known as Robust Dropseed, is a semi-deciduous perennial grass native to savannas, open woodlands, and semi-desert regions in Western Africa and the Canary Islands. It typically grows to a height of 1-4 feet (0.3-1.2 meters) and can spread to about 3 feet (0.9 meters) wide. The grass features fine-textured foliage that forms dense tufts, and it produces airy panicles of small flowers that may go unnoticed. The flowering season occurs in late summer to fall, and while the flowers are not particularly showy, they add a delicate texture to the landscape.

Robust Dropseed is valued for its drought tolerance and its ability to thrive in poor soils, making it an excellent choice for xeriscaping and naturalized areas. It is often used for erosion control, as a ground cover in dry gardens, or as an accent plant in mixed borders. This grass prefers full sun exposure and requires minimal water once established, making it a low-maintenance option for gardeners. It is adaptable to a range of soil types, provided they have good drainage. While generally disease-free, it can occasionally suffer from rust if conditions are too moist.CC BY-SA 4.0
