Other members of the Cyperaceae family are also called sedges, however those of the genus Carex may be called "true" sedges, and it is the most species-rich genus in the family. The study of Carex is known as caricology. All species of Carex are perennial and typically have rhizomes, stolons or short rootstocks, although some species grow in tufts. Carex species and cultivars are popular in horticulture, particularly in shady positions.   
  A delightfully attractive ornamental grass with thin, ‘hair like’ arching, silvery green leaves that looks best in mass plantings, Carex comans Green grows to a height of 30-35 cm. This grass prefers full sun to partial shade and moist, well-drained soil. It has slender arching, grassy leaves that grows in a wide clump that resembles a fountain. They are silvery-green and seem to shimmer when blown by a breeze or, if planted in pots, resemble falling water with the leaves draped over the pot. Though it resembles an ornamental grass, it comes from a different family all together, and like many of its fellow sedges, is more versatile than grasses, being tolerant of both full sun and partial sun and moist to almost-wet soils. They are evergreen in warm climates, perennial in colder climates, where they wither and brown in autumn but nonetheless lend color to the winter garden. Remove the brown leaves in late winter to make way for the new leaves in spring. Grow this plant in sun to partial shade in moist, well-drained soil. Use it for its contrasts of texture and habit in containers, mixed beds and mixed borders. Or plant it as edging for walkways or massed as a groundcover. Plants live on average about 4 years, so dividing the plants in the spring will keep the plants looking fresh.
