Scirpus Cyperinus, commonly known as wool grass, is a type of wetland sedge plant that is found in boggy areas across North American. Wool grass is a popular plant that provides a range of ecosystem services, including water filtration, erosion control, and habitat creation for aquatic species. Some common synonyms for wool grass include bulrush, cattail, bulrush sedge, and club-sedge. These terms typically refer to other common sedge species that are similar in appearance and ecology to wool grass. Despite these similarities, each species has their unique characteristics and ecological roles within wetland ecosystems.
