Luzula

Luzula is a genus of flowering plants in the rush family Juncaceae, commonly known as woodrush. The genus comprises roughly 60 species of tufted perennials native to temperate regions of the Northern Hemisphere, with a range extending into alpine zones. Luzula plants form clumps from fibrous rhizomes and have slender, grasslike leaves.

Leaves are linear to narrowly lanceolate, usually evergreen in mild climates. They can be stiff and somewhat glossy, with margins that are sometimes finely hairy. The inflorescences are slender panicles bearing small, inconspicuous flowers that are typically greenish or brownish and wind-pollinated. Fruits are small capsules opening through three-part valves.

Habitat and ecology: Luzula species are commonly found in woodlands, meadows, stream banks, and damp grasslands. Many prefer moist, well-drained soils and partial shade, though some alpine or tundra-adapted forms tolerate cold, windy sites. They are valued for their evergreen foliage and tolerance of shade and poorer soils.

Cultivation and use: Luzula are used ornamentally in shade gardens and woodland plantings, where they can form effective groundcovers and provide year-round foliage. Propagation is by division in spring or autumn or from seed. Some species can spread aggressively, so cultivators may need to manage spread in garden settings.
