Slender Sedge (Carex praegracilis)

Clustered field sedge (Carex praegracilis) is a tough, adaptable species in the sedge family (Cyperaceae), native to much of North America, except for the southeastern region. It thrives in wet and seasonally wet environments, including meadows, riverbanks, and wetlands, and can even grow in clay hardpan soils. This sedge spreads readily by underground rhizomes, making it useful for erosion control on slopes. It also serves as an excellent lawn alternative, requiring significantly less water than traditional turfgrass. It can be mowed, tolerates moderate foot traffic, and works well in poorly draining areas or between pavers. From Calscape.
