Snowy woodrush

Sun

Partial shade is best; tolerates deeper shade and full sun where summers are cool and the soil stays moist.

Water

Moderate; keep evenly moist while establishing, then water during prolonged dry spells. Established plants tolerate some dry shade.

Soil

Humus-rich, well-drained soil; tolerates clay, loam and sandy soil if moisture is adequate. Acid to neutral soil is ideal.

Height

1.5-2 ft (0.45-0.6 m), including flower stems

Spread

1-1.5 ft (0.3-0.45 m)

Flowers

Late spring to midsummer; airy clusters of small creamy-white flowers that age to pale brown.

Foliage

Narrow, arching, dark green leaves with conspicuous white hairs along their edges; evergreen, though foliage may look battered after a hard winter.

Growth

Moderate

Growth rate

Moderate

• Water regularly through the first growing season, especially beneath trees.
• Spread a thin layer of leaf mould or compost around clumps in spring, keeping the crown uncovered.
• Water established plants during extended drought if leaves begin to curl or brown.
• Remove flower stems before seed ripens if you want to limit seedlings.
• Divide crowded clumps in spring, replanting the divisions promptly.

Pruning. In late winter or early spring, remove dead leaves by hand or cut out damaged foliage near its base without cutting into the crown. Cut spent flower stems to ground level after flowering, or leave them until autumn for their pale seedheads.

Late winter

Remove dead or winter-damaged foliage before fresh growth develops.

Spring

Plant or divide clumps, water thoroughly and mulch lightly with leaf mould.

Late spring

Check soil moisture as flower stems develop, particularly beneath trees.

Summer

Water during prolonged drought and remove fading flower stems if seedlings are unwanted.

Autumn

Remove unwanted seedlings and plant new clumps while the soil is moist and workable.

• Plant in repeated groups along shaded paths for a soft, evergreen edge.
• Use beneath deciduous trees with ferns and spring bulbs to link seasonal displays.
• Thread through woodland borders with hostas and hardy geraniums for contrasting leaf shapes.
• Combine with white-flowered shade plants to brighten a sheltered courtyard or white garden.

Garden styles it suits: Woodland, White garden, New perennial (prairie), Cottage garden, Low-maintenance and Green on green.

Plant it with: Hostas, Epimediums, Hellebores, Japanese painted ferns, Siberian bugloss and Snowdrops.

Wildlife: Dense clumps provide shelter for small invertebrates. The flowers are wind-pollinated and are not a significant nectar source for pollinators.

• Brown leaf tips or scorched foliage: improve soil moisture and provide afternoon shade, especially in hot climates.
• Crown rot in waterlogged soil: improve drainage and avoid burying the crown under soil or mulch.
• Unwanted seedlings: remove flower stems before seed ripens and pull young seedlings while small.
• Sparse flowering in deep shade: move to a position with brighter filtered light.

Not known to be toxic to people, cats, dogs or horses; no particular part is recognised as poisonous. It is not an edible plant, and specific animal-safety information is limited.

• Greater woodrush (Luzula sylvatica)

  Has much broader leaves and brownish flower clusters rather than conspicuous creamy-white flowers.

• White woodrush (Luzula luzuloides)

  Also has hairy-edged leaves, but its flowers are usually smaller and less densely clustered, giving a less showy, more open display.

The species name nivea means snow-white, referring to the pale flowers that also give snowy woodrush its common name.

Propagation. Divide established clumps in spring. Alternatively, sow ripe seed in pots in a sheltered outdoor position; seedlings may also appear around established plants.

Accepted botanical name

Luzula nivea

Native range

Austria, France, Germany, Italy, Spain, Switzerland and Yugoslavia.
