Carex hystericina

Common name: Porcupine Sedge

Native plant

An interesting clumping sedge that has more landscape potential than most people expect. The culm bear dangling spikelets of bristly fruit that are very intersting even when viewed from a short distance. Great for ornamental use in rain gardens or wet pollinator gardens. In nature, look to find this beauty in moist prairies and other wet(ish) places in NE Illnois and in swales in wet areas in the Dunes.
