Carex pensylvanica, or Oak Sedge, forms fine textured, deep green, slowly spreading plants with a tough constitution. Carex pensylvanica makes a great ground cover that has a flowing, wave-like form. Oak sedge is semi-evergreen and can provide both food and shelter for small birds.
It makes an excellent ground cover for dry, part sun to shady areas. Carex pensylvanica is native to the eastern and central U.S. and Canada. Drought tolerant, once established. Try this one under trees where grass won't grow.
