Notes
Fruiting April to June
Wetland indicator: NA
Most sedges are difficult to identify without examining the perigynia, but this woodland sedge is quite distinct. Only a few sedges have leaves this broad and this is the only one that is deep green without a waxy appearance to the leaves. The leaves also tend to have a crinkly appearance which can help distinguish it from C. careyana. Another common name, seersucker sedge, is a reference to the similarity of the leaves to the puckered surface of seersucker fabric.
