Clustered Field Sedge (
Carex praegracilis
) is a species in the Cyperaceae (Sedge) family. It is native to much of North America, from Alaska across southern Canada and throughout the continental United States, except for the southeastern region.
It grows in wet and seasonally wet environments in a number of habitats, including meadows and wetlands; it is often riparian or semi-riparian in the drier parts of its range. It tolerates disturbed habitat such as roadsides and thrives in alkaline substrates.
This sedge produces sharply triangular stems from a network of thin, coarse rhizomes. The flower cluster is a dense, somewhat cylindrical array of flower spikes.
The plant is often dioecious, meaning that an individual plant will bear male or female flowers in its flower clusters but not both. It spreads readily by rhizomes. In the garden, it can be useful in poorly draining areas, in the spaces between pavers, and as a replacement for non-native lawn grasses. It has a soft texture, can be mowed, and requires significantly less water than turfgrass.
