Wheat sedge is a tall, robust grass-like perennial that forms substantial clumps in moist to wet areas. This native sedge produces distinctive wheat-like seed heads during summer months and thrives in consistently moist soils. It works well for rain gardens, pond edges, or other areas with reliable water sources.
