Sedge is a type of grass-like plant that typically grows in wet areas, such as marshes and along the edges of ponds. These plants have triangular stems and often produce clusters of small flowers. Sedges are important for the environment because they help prevent soil erosion and provide habitat for various animals, including birds and insects. There are many different species of sedge, and they can be found all over the world. Some common types include Carex and Schoenoplectus. Gardeners often use sedges in landscaping because they are hardy and can thrive in challenging conditions, adding beauty and texture to gardens and natural areas.
