Willd. }}Carex livida is a species of sedge known by the common names livid sedge and pale sedge. It has a scattered, interrupted circumboreal distribution, occurring throughout much of Eurasia and northern North America.[1] It also occurs in Panama and South America.[2] It is extirpated in California.[3] This sedge forms small clumps of stems up to 50 to 55 centimeters tall. The stiff, leathery leaves are a pale, waxy blue-gray and have channels on their surfaces. The inflorescence contains separate pistillate and staminate spikes. The plant spreads mostly by sprouting from its rhizome, but it also produces seed.[1][2] This plant grows in wet substrates with groundwater at the surface. The soils are often calcareous and rich in nitrogen. It can typically be found in fens and bogs with sphagnum mosses and other sedges.[1] References1. ^1 2 Williams, Tara Y. 1990. Carex livida.
