|C. flaccosperma is native to calcareous woods in eastern North America, forming loose tussocks of green to glaucous blue-green leaves, 5/8 inch wide. Relatively insignificant flowers appear in early spring. Basal leaves last through winter. 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 arraged 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.
