Long-stolon sedge is a loosely caespitose, perennial graminoid. It is low to medium statured compared to other Carex. Culms are 4 to 20 inches (10-50 cm) long. Leaves are slender, stiff, and wiry. Old, dead leaves are persistent, often forming fibrous tufts at the stem base. Inflorescences are terminal staminate and pistillate spikes. Male spikes may be pediceled above female spikes. The fruit is a hairy achene ranging from 1.6 to 2.5 mm long. Seedheads bear 5 to 15 fruits each.
