|C. digitata a member of the Sedge family (Cyperaceae) is as widespread as the grass family, but are especially common in wet or moist habitats in temperate and subarctic zones. The stems of sedges are solidly filled with pith, and do not have nodes. They are triangular in cross section. The leaves are arranged in three rows, with sheaths usually fused around the stem. Leaf blades of sedges are usually grass-like; with evergreen or semi-evergreen foliage. Sedges are wind-pollinated, with flower-heads almost always in spikelets. This is a reliable, tufted ground cover, semi-evergreen in milder climates. Leaves are dark green, to 3/16 inches wide.
