Juncus is a genus of flowering plants commonly known as rushes. These plants are typically found in wetland areas, such as marshes and along the edges of ponds. They have long, slender stems and can grow in clumps, providing habitat for various wildlife. Rushes are often used in landscaping and erosion control due to their ability to thrive in saturated soils. They play a crucial role in maintaining water quality by filtering pollutants and providing stability to the soil. Some species of Juncus are also used in traditional crafts, such as basket weaving.
