Distributed from southeast North Carolina south to Florida and west to Louisiana.[1]



Carex verrucosa are sedges that are almost restricted to wet savanna communities.[2] Thrives in wetland depressions in the southeastern coastal plain.[3] This species is found in sphagnum bogs in pine woods depressions, cypress ponds, and sweetbay-titi swamps. It is tolerant a range of light levels, from shady to sunny. It grows in sandy loam and peaty soils that are wet to saturated. Also found in roadside ditches.[4]

Associated species includes Carex walteriana, Ilex myrtifolia, Lyonia, Panicum hemitomon, Polygala cymosa, Pontederia, Rhynchospora corniculata, Taxodium distichum, and others.[4]


The inflorescence is arranged in a spike. It has superior ovaries. C. verrucosa has been observed flowering from February to July, and also in October and November with peak inflorescence in April and May.[5][4] The fruit is a nutlet.[1]
