Leatherleaf sedge

Sun

Full sun to partial shade; foliage colour is usually strongest in sun. Afternoon shade helps in hot climates.

Water

Keep the soil moderately moist, especially during establishment. Established plants tolerate brief dry spells, but prolonged drought can damage the foliage.

Soil

Moisture-retentive but well-drained soil; tolerates clay, loam and sandy soil if drainage is adequate. Avoid stagnant, waterlogged ground.

Height

1-2 ft (0.3-0.6 m)

Spread

1-2 ft (0.3-0.6 m)

Foliage

Evergreen. Very narrow, coppery bronze to cinnamon-brown leaves form an upright tuft, with fine, curled tips. Older leaves arch outward.

Growth rate

• Water regularly during the first growing season, allowing surplus water to drain away.
• Water established clumps during prolonged dry weather and check containers frequently.
• Apply a thin layer of compost in spring; avoid heavy nitrogen feeding.
• Keep mulch clear of the crown to reduce the risk of rot.
• Divide congested or declining clumps in spring, retaining healthy outer sections.

Pruning. In early spring, gently comb out loose dead leaves with gloved hands and snip damaged foliage at the base. Do not routinely shear the whole clump to the ground, as this evergreen sedge can recover slowly.

Early spring

Remove loose dead leaves and check the crown for winter damage or rot.

Spring

Plant new specimens or divide established clumps as growth resumes.

Late spring

Apply a light compost dressing and replenish mulch without covering the crown.

Summer

Water during extended dry spells, particularly in pots and newly planted borders.

Autumn

Remove unwanted seedlings and clear fallen leaves that smother the clump.

Winter

Keep drainage outlets clear and protect containers from prolonged saturation and severe freezing.

• Repeat small groups along a path to create a copper-coloured rhythm without a tall screen.
• Combine with silver-leaved perennials and green foliage for clear colour and texture contrasts.
• Use in containers where its upright leaves and curled tips can be seen close up.
• Plant among rocks or in a gravel-mulched border where the underlying soil retains some moisture.
• Mix into perennial borders to retain structure after deciduous plants die back.

Garden styles it suits: Modern, Architectural minimal, New perennial (prairie), Dry gravel garden, Winter interest and Small-space.

Plant it with: Coral bells, Lamb's ears, Hardy geraniums, Japanese anemones, Purple coneflower and Dwarf New Zealand flax.

Wildlife: The dense foliage offers shelter for small invertebrates. Flowers are wind-pollinated and provide little value as a nectar source.

• Crown or root rot in saturated soil: improve drainage, keep mulch away from the crown and replace badly rotted plants.
• Bleached, brittle leaves during drought: water deeply and provide afternoon shade in hot locations.
• Winter scorch or frost damage: choose a sheltered position and remove damaged leaves in spring.
• Unwanted self-seeding: remove flowering stems before seed ripens and pull seedlings while small.

Not known to be toxic to people, cats, dogs or horses. No part is recognized as poisonous, though the narrow leaf edges can scratch skin and chewing fibrous leaves may cause digestive upset.

• Weeping brown sedge (Carex flagellifera)

  Usually forms a looser, more arching mound with long, trailing leaves; leatherleaf sedge has a more upright outline and conspicuously curled leaf tips.

• New Zealand hair sedge (Carex comans)

  Has finer, softer-looking leaves that arch into a low, flowing mound rather than the relatively stiff, upright tuft of leatherleaf sedge.

• Orange New Zealand sedge (Carex testacea)

  Typically has olive-green foliage flushed orange, especially in sun, and a more arching habit; leatherleaf sedge is more consistently copper-brown.

The species name buchananii honours John Buchanan, a botanist and botanical artist who worked in New Zealand.

Propagation. Divide healthy clumps in spring and replant promptly, keeping divisions moist while they establish. It can also be raised from seed, although seedlings may vary in foliage colour.

Accepted botanical name
