Blue Sedge vs Tarheel Sedge
This guide is under construction and has not been published yet. It may have errors. When in doubt, double-check other sources for definitive ID.Although these species have little range overlap, they do overlap in eastern Virginia. They are closely-related and visually similar, and can be hard to tell apart. They can be reliably distinguished by the ratio of spike length to the number of seeds in each spike. C. pigra is less restricted to acidic soils and more likely to occur on moister sites, whereas C. glaucodea is restricted to acidic soils and occurs on sites that are drier on average.
