Luzula is a genus of flowering plants in the rush family Juncaceae.

The genus has a cosmopolitan distribution, with species occurring throughout the world, especially in temperate regions, the Arctic, and higher elevation areas in the tropics.

[2] Another etymology sometimes given is that it does derive from lucciola but that this meant a mid-summer field, or from the Latin luculus, meaning a small place; the same source also states that this name was applied by Luigi Anguillara (an Italian botanist) in 1561.

They generally form clumps of cylindrical stems and narrow leaves with hair-lined edges.

Some species, notably Luzula sylvatica and its cultivars, are used as ornamental garden plants.
