Sporobolus rigidus, commonly known as Prairie Sandreed, Rigid Dropseed, Rigid Sporobolus, or Rigid Rushgrass, is a perennial grass that is indigenous to a variety of habitats including grasslands, open woodlands, and coastal dunes in North America. It typically grows to a height of 1.5-2.5 feet (0.46-0.76 meters) and is characterized by its stiff, upright growth habit and fine-textured foliage. The plant produces inconspicuous greenish flowers during the summer months, which are followed by small, hard seeds that contribute to its spread.

Prairie Sandreed is valued for its drought tolerance and ability to stabilize soil, making it an excellent choice for erosion control in sandy areas. It is also used in naturalistic plantings and as a low-maintenance ground cover in xeriscapes. This grass thrives in full sun and is adaptable to a range of soil types, preferring medium to fast-draining sandy or loamy soils. It requires minimal water once established, reflecting its adaptation to arid environments. While generally disease-free, it can occasionally suffer from rust in humid conditions.CC BY-SA 4.0
