This deciduous species of Flat Sedge from the USA was described by Linnaeus in 1753 already. It looks like a dwarfing form of the Egyption Papyrus Grass, but tolerates temperatures to minus 12 °C. The typical, bright green leaf-whorls appear on up to 60 cm tall stems. The brown flowers (end of spring/beginning of summer) appear in spikes. The plant shrives in nutritious, eventually limy soil in water to a depth of 5 cm. Droughts are taken badly.
