Unlike most grass-like plants, this sedge is insect-pollinated and has developed showy white colorization on the bracts that surround its cluster of flowers in each head. The edges of the white bleed into the green color so it looks like Mother Nature spray-painted the white as an afterthought.
These sedges are a good addition to the edges of ponds or rain gardens. They are attractive, interesting, and tough. They can live in standing water, but they can also withstand drought. So add some to your landscape this year.
Here's the old rhyme to remember the characteristics of each.
Sedges have edges,
Rushes are round,
Grasses have nodes
all the way to the ground.
Sedges have triangular stems (edges) and the famed saw grass of the Everglades (Cladium jamaicense) is sedge, not a grass and because of a high silicone content in those "edges" it can saw right through your skin.
