Common Bur Sedge

Carex grayi

Common Bur Sedge, also called Gray's Sedge, stands out in wetland landscapes due to its distinctively bold, star-shaped seed heads. It forms dense clumps of broad, arching green leaves, reaching up to 3 feet in height. The bright green flower spikes transform into striking, spiky seed heads in late summer, adding visual interest and a whimsical touch to the garden. Ideal for rain gardens, pond edges, and moist garden beds.
