Bolboschoenus robustus, commonly known as Seacoast Bulrush, is a semi-deciduous perennial grass that thrives in freshwater and brackish marshes, wet meadows, and along the margins of ponds and streams. Its native range extends through the Southeastern United States, California, parts of Mexico, South America, and the Caribbean. This species typically reaches a height of 4-5 feet (1.2-1.5 meters) with a width of 3 feet (0.9 meters). The plant features stiff, upright stems and inflorescences that consist of clustered spikelets, which are brownish-green and not particularly showy. It flowers in the summer months and can produce a significant amount of seeds, which are important food sources for wildlife.

Seacoast Bulrush is valued for its ability to stabilize soil and filter water, making it an excellent choice for riparian restoration projects and naturalized water gardens. It is also used in constructed wetlands for wastewater treatment. In cultivation, it requires full sun to part shade, consistent moisture, and can tolerate standing water, making it suitable for pond edges and water features. While it prefers soils with slow drainage, it is adaptable to various soil types as long as they remain wet. Gardeners should be aware that in ideal conditions, it can spread aggressively through rhizomes and self-seeding, potentially becoming invasive outside its native range.CC BY-SA 4.0
