Notes

Fruiting late May to July

Wetland indicator: OBL

A very common species, particularly in disturbed areas of moist woods. Also called Bottlebrush Sedge, but there are other sedges given this name (C. comosa and C. hystericina). The latter is similar but has at least the lowest pistillate spike spreading or drooping on a slender peduncle. Carex baileyi looks very much like C. lurida but has narrower leaves and longer, more abruptly beaked perigynia.
