Comments

This is one of the first sedges to bloom during the spring. Pennsylvania Sedge is very similar to Carex lucorum and Carex heliophila (Sun Sedge); these latter two species are sometimes considered different varieties of Pennsylvania Sedge (e.g., Carex pensylvanica distans & Carex pensylvanica digyna respectively). Compared to Pennsylvania Sedge, these species/varieties have longer perigynia (3.0–4.0 mm. in length). The perigyneal beaks of Carex lucorum are more slender and longer than those of Pennsylvania Sedge, while Sun Sedge has leaf blades that are more stiff and revolute (rolled). Another similar species, Carex communis, lacks the long stolons of Pennsylvania Sedge. Most of these species prefer similar habitats to Pennsylvania Sedge, although Sun Sedge is more common in the shorter prairies of the Great Plains states.
