Because of its early growth, Capitate Sedge is more conspicuous during the spring. At this time, its fertile culms will form short dense heads of spikelets, unless they become decapitated by a lawn mower or a cow. A second attempt to bloom will occur during the early summer if the first attempt fails. Because this sedge is similar in appearance to several others, it can be difficult to identify. It is more likely to be found in lawns and other mowed areas than these other sedges, however. Capitate Sedge can be distinguished by its small dense clusters of spikelets (about 5-8 spikelets per inflorescence), fewer leaves (about 3 along the lower third of each culm), and smaller perigynia (up to 3 mm. long & 2 mm. across). These perigynia are unusually smooth and delicate in appearance. Sedges that are similar to Capitate Sedge include Carex mesochorea (Midland Sedge) and Carex leavenworthii (Leavenworth's Sedge). Midland Sedge has more leaves (about 5-7) and larger perigynia (up to 4 mm. long and 2.5 mm. across) than Capitate Sedge. Leavenworth's Sedge has more narrow leaves (up to 3 mm. across), perigynia that are more rounded at the bottom (even slightly cordate at the base), and pistillate scales that lack long slender tips.
