Cladium mariscoides, commonly known as smooth sawgrass, is a perennial herb native to wetland habitats across eastern North America, including freshwater marshes, sedge meadows, and wet prairies. It can grow up to 39 inches (1 meter) tall and spreads through rhizomes, forming dense stands. The plant is characterized by its very narrow, grass-like leaves and chestnut brown spikelets that are arranged in a branched panicle, typically blooming in the summer months. The flowers are not particularly showy, but they do add a subtle texture to the wetland landscape.

Smooth sawgrass is valued for its role in wetland ecology, providing habitat and food for wildlife. It is also used in restoration projects to stabilize soil and filter water. In cultivation, it requires consistently moist to wet soil conditions and can tolerate a range of light exposures from full sun to part shade. While not commonly used in traditional garden settings, it is an excellent choice for naturalized areas, rain gardens, and water features. Gardeners should be aware that it can spread aggressively in ideal conditions, potentially becoming invasive in areas outside its native range.CC BY-SA 4.0
