Sedges are a type of grass-like plant that typically grow in wet areas, such as marshes and along riverbanks. They belong to the family Cyperaceae and are known for their triangular stems and narrow leaves. Unlike true grasses, sedges often have a more rigid structure and can provide important habitats for wildlife, including birds and insects. These plants play a vital role in ecosystems by helping to prevent soil erosion and filtering water. Sedges can also be used in landscaping and gardening for their unique textures and colors. Some common types of sedges include Carex and Schoenoplectus, which are often found in natural wetlands.
