segge

Segge is the common German name for sedges, plants in the family Cyperaceae, especially the genus Carex. In English, the term sedge covers most of these species. Segges are herbaceous perennials that resemble grasses but typically have solid, often triangular stems and leaves arranged around the stem. The inflorescences are usually composed of spikelets and are often inconspicuous; fruits are small, hard nutlets.

Segges are widespread in wetlands and damp habitats, including marshes, riverbanks, lake shores, and damp meadows. They play ecological roles in stabilizing soils, filtering water, and providing cover for invertebrates and birds. Many species tolerate periodic flooding and nutrient-poor soils. The genus Carex is large and diverse, with hundreds to thousands of described species worldwide; taxonomy can be complex and region-specific.

Uses and cultivation: Segges are valued in horticulture as ornamental plants and groundcovers, with several species bred for gardens, borders, and container plantings. They are also employed in naturalistic planting schemes and habitat restoration for erosion control and landscape stabilization. In some cultures, sedges have traditional uses in weaving mats, baskets, and thatching materials.

Selected species commonly found in cultivation include Carex morrowii (Japanese sedge) and Carex pendula (pendulous sedge). See also sedges, Carex, Cyperaceae.
