The Juncaceae, the rush family, are a monocotyledonous family of flowering plants of eight genera and about 400 species. Members of the Juncaceae are slow-growing, rhizomatous, herbaceous plants, and they may superficially resemble grasses and sedges. They often grow on infertile soils in a wide range of moisture conditions. The most well-known and largest genus is Juncus. Most of the Juncus species grow exclusively in wetland habitats. A few rushes are annuals, but most are perennials.
