Luzula nivea aka Lesser Wood Rush

Luzula nivea is an evergreen perennial in the rush family, Juncaceae. Its common names include snowy wood-rush and snow-white wood-rush. It comes from the Pyrenees and Alps in Europe. It is not native to Britain or Ireland. This plant keeps its leaves through the year. Both its green leaves and white flowers add garden interest.

The plant spreads slowly and forms a loose, rounded clump. Its narrow leaves are dark green. They reach about 1 foot (0.3 m) long. RHS gives a garden height of 1.6–3.3 feet (0.5–1 m). Its spread ranges from 0.3–1.6 feet (0.1–0.5 m). Plants reach their mature size in two to five years. The flower stems reach about 2 feet (0.6 m). Small white flowers have a sheen and grow in loose clusters. They stand above the clump of leaves. RHS places flowering in early and mid-summer. Chicago Botanic Garden lists bloom from March through June. The sources therefore give somewhat different flowering seasons.

Choose a site with partial or deep shade. Both garden sources list shade as a suitable exposure. Sun is also possible where the soil stays moist. RHS recommends humus-rich soil with low to moderate fertility. Clay, loam, and sand are all suitable soil types. The plant accepts acid, neutral, and alkaline soil. Give it moisture with good drainage rather than standing water. RHS rates its winter hardiness as H5. Chicago Botanic Garden lists USDA zones 4–6. These ratings describe hardiness under their respective regional systems.

Use this wood-rush as ground cover or in beds and borders. Chicago Botanic Garden also lists it as a specimen plant. RHS includes cottage gardens and informal planting among its uses. Its loose clumps suit these settings without needing formal shaping. The leaves remain green beyond the flowering season. The white flower clusters add a separate season of interest.

Routine pruning is not needed. RHS reports few usual pest or disease problems. Raise new plants from seed in outdoor containers. Sow in spring or autumn. Another option is division from mid-spring to early summer. These simple care needs make it a low-maintenance choice for suitable sites. The supplied sources give no information on edible parts or toxicity.
