I saw a mass planting of this Gray's or Morningstar or Common Bur Sedge at the large parking lot on the east side of Morton Arboretum in Lisle, IL, in June 2015. Looks good as a grass-like mass. Its perigynia, the sacs covering the fruit, are pointed and they point in all directions, up, sideways, and down. The similar species of the Greater Bladder Sedge, Carex intumescens, has its perigynia point up and to the side, not down.
