Similar to J. dicotomus but has many flowers per subtending stalk and its capsules are reddish brown, while J. dicotomus has only one flower per stalk and its capsules are straw colored at maturity. It is sometime separated from Juncus biflorus by authors who consider J. marginatus to be smaller (to 3') and without rhizomes while J. biflorus grows to over 4' and is rhizomatous. No septa. Stem somewhat flattened, closely resembles a grass, leaves very shiny, without obvious veins. (Look-a-likes – grasses with flat stems at base – Echinochloas, Panicum rigidulum, Setaria glauca)
The seeds of most species of Juncus may be planted fresh or after cold/moist stratification, and require light for germination (Steffen 1997).
Found in moist soils throughout Louisiana and most of Texas, especially the eastern half. Ranges throughout the eastern half of North American.
Moist, sandy, or peaty soil, stream and lake margins, wet prairies, ditches, at margin or in open woods.
