Reeds are tall, slender plants that typically grow in wetlands, marshes, and along the edges of rivers and lakes. They belong to the family Poaceae, which includes grasses. Reeds have hollow stems and can reach heights of several feet. They play an important role in their ecosystems by providing habitat for wildlife and helping to stabilize soil. Common types of reeds include common reed (Phragmites australis) and bulrushes. Reeds are often used in construction, crafts, and as a natural material for making thatched roofs. Additionally, they can help filter water and improve water quality in their environments.
