Salt-marsh bulrush is a native sedge which may first be noticed growing along the edges of brackish and saline coastal marshes nearly throughout Florida (Wunderlin, 2003). Scirpus robustus blooms from spring to fall and occurs almost always under natural conditions in wetlands. They have very large conspicuous, cone-shaped spikelets, and long thin leaves and bracts. Its many seeds are an important food to ducks, geese and other water birds.
