Juncus roemerianus

Black needlerush, black rush

Native to Florida

Species Overview

This salt-loving “leafless” rush can cover large areas in coastal salt and brackish tidal marshes, and is easily recognizable by its characteristic grayish-green to blackish hues. Its “stem tips” are very sharp pointed and stout. “Stems” in this species are actually leaves that are rounded so tightly that they appear to be very sharp-pointed stems. This Juncus is one of 21 species located in Florida (Wunderlin, 2003). Black needlerush occurs in the southern US, and extends north to DE and west to TX (Kartesz, 1999).
