Two-foot-tall, stiff, orange-brown blades curve at the end like a shepherd’s staff. Burnished red-bronze foliage, which fades to flax at the tips, gives off a warm glow when backlit by the sun.

This sedge is one of the most adaptable of the ground-cover grasses. Its ability to look the same in sun or shade makes it a valuable asset in plantings that go in and out of full sun. Berkeley sedge is a good solution for areas under stress where lawn grasses often fail. The flowers are not particularly noteworthy.

This beautiful sedge's vivid foliage adds bright color to the garden. The yellow seems to glow in partial shade. Use this dramatic clump of foliage near water or in shallow water, or in another moist location.

'Ice Dance' is a descriptive name for this eye-pleasing sedge. While the early-spring flowers are insignificant, the strappy leaves are striped with a clean white edge and complement just about any companion. 'Ice Dance' is evergreen and adds a sense of permanence to the winter shade garden. Remove any tattered leaves in early spring and then let it go for the rest of the growing season.

'Ice Dance' is a dense, spreading sedge grown for its foliage that has creamy-white margins and dark green centers. Stems are triangular compared to rounded grass stems. Flower stems are solid without nodes (compared to grasses, which are usually hollow with nodes). The flowers are insignificant. This sedge is evergreen in warm climates. Grow as a groundcover in woodland areas or in a shade garden.
