Carex firma forms thick cushions. Its leaves are up to 8 centimetres (3.1 in) long in normal conditions (up to 10 cm or 4 in in moist, sheltered localities), dark green and stiff.[1] The stems are up to 20 cm (7.9 in) tall (exceptionally 30 cm or 12 in), but always at least twice as long as the leaves.[1]
In synecology, Carex firma is a characteristic part of the "Caricetum firmae" (also called "Firmetum"), which is an important community in the alpine zone over calcareous rock.[2]
Carex firma can survive temperatures as low as −50 °C (−58 °F).[3]
Carex firma was first described by Nicolaus Thomas Host in 1797, in his work Synopsis Plantarum in Austria provinciisque adjacentibus sponte crescentium.[4]
