Zebra grass

Sun

Full sun is best; light shade is tolerated, but stems may flop and flowering is reduced.

Water

Water regularly during the first growing season. Once established, water deeply during prolonged dry spells; it tolerates some drought but grows best with consistent moisture.

Soil

Moderately fertile, moist but well-drained soil. Tolerates clay if it does not remain waterlogged, and accepts acidic, neutral or alkaline conditions.

Height

5-8 ft (1.5-2.4 m), including flower stems

Spread

4-6 ft (1.2-1.8 m)

Flowers

Coppery-pink plumes in late summer to autumn, fading to silvery cream; flowering may be sparse or absent in cool, short summers.

Foliage

Long, arching green blades with irregular horizontal yellow bands that become more noticeable as the season progresses; turns straw-coloured after frost.

Growth

Moderate to fast once established; new shoots emerge relatively late in spring.

In the garden

Spreads vigorously: plan to contain it.

Growth rate

Fast

• Plant in spring with enough room for a mature clump, away from narrow paths where the leaves can brush against skin.
• Water deeply through the first growing season and during extended drought thereafter.
• Apply a light compost mulch in spring, keeping it clear of the crown; avoid heavy nitrogen feeding, which encourages floppy growth.
• Use a discreet support ring early in the season if the site is exposed or stems regularly lean.
• Divide congested clumps in spring when the centre becomes sparse or growth weakens.

Pruning. In late winter or early spring, before new shoots emerge, cut old stems and leaves to 4-6 in (10-15 cm) above the ground. Wear gloves and long sleeves; where self-seeding is a concern, remove flower heads before seed ripens.

Late winter

Cut down the previous year's stems before fresh shoots appear.

Spring

Plant or divide clumps as growth begins, then water thoroughly.

Spring

Apply a light compost mulch and install supports if needed.

Summer

Water during prolonged dry spells and check for leaning stems.

Late summer

Remove developing flower heads before seed ripens where escape is a risk.

Autumn

Leave dry foliage standing for winter structure if it remains upright and seed spread is not a concern.

• Place at the back of a sunny mixed border, with shorter perennials hiding the lower stems.
• Use as a seasonal screen beside a terrace, allowing space for the arching leaves and the winter cutback.
• Repeat a few widely spaced clumps in a large border for rhythm and contrasting horizontal leaf markings.
• Combine with coneflowers, black-eyed Susans and tall sedums for late-summer flowers against textured foliage.

Garden styles it suits: Architectural minimal, New perennial (prairie), Japanese, Modern, Autumn colour and Winter interest.

Plant it with: Purple coneflower, Black-eyed Susan, Tall sedum, Russian sage, Verbena bonariensis and New England aster.

Wildlife: Dense clumps can shelter insects and other small animals, and birds may take ripe seed. Flowers are wind-pollinated and offer little nectar value; this non-native grass is not a substitute for locally native habitat plants.

• Flopping stems: provide full sun, avoid rich feeding and use an early-season support ring if necessary.
• Dead or thinning clump centre: divide in spring, discard the exhausted centre and replant vigorous outer sections.
• Crown rot in wet ground: improve drainage or move the plant; avoid sites that stay saturated through winter.
• Miscanthus mealybug: pale, distorted growth and white waxy insects inside leaf sheaths can indicate infestation; avoid moving affected divisions and seek locally approved treatment advice.

Not known to be toxic to cats, dogs, horses or people. No part is recognised as poisonous, but the stiff, sharp-edged leaves can cut skin or irritate the mouth if chewed.

Where it spreads. Miscanthus sinensis is listed as invasive in parts of the eastern and midwestern United States, including North Carolina, Virginia and Pennsylvania, and is regarded as an environmental weed in parts of New South Wales, Australia. 'Zebrinus' is not reliably sterile and may produce viable seed, particularly in long, warm growing seasons. Check local guidance before planting;

• Porcupine grass (Miscanthus sinensis 'Strictus')

  Has similar horizontal yellow bands but a noticeably stiffer, more upright habit; zebra grass has more arching, drooping leaves.

• Variegated maiden grass (Miscanthus sinensis 'Variegatus')

  Its creamy-white stripes run lengthwise along the leaves rather than across them.

• Little Zebra grass (Miscanthus sinensis 'Little Zebra')

  Has similar cross-banded foliage but forms a much shorter, more compact clump, usually about 3-4 ft (0.9-1.2 m) tall in flower.

The common name and cultivar name 'Zebrinus' refer to the zebra-like bands across the leaves, while sinensis means 'from China'.

Propagation. Divide in spring as shoots begin to emerge, using a sharp spade or saw to separate rooted outer sections. Division preserves the striped cultivar; seedlings do not reliably come true.
