Heavenly bamboo

Sun

Full sun to partial shade; autumn and winter colour is usually strongest with several hours of sun. Give afternoon shade in hot, dry climates.

Water

Water regularly during the first growing season. Once established, water during prolonged dry spells; container plants need more frequent watering.

Soil

Moist but well-drained soil, preferably slightly acidic; tolerates a range of soils but dislikes persistent waterlogging.

Height

6-8 ft (1.8-2.4 m)

Spread

3-5 ft (0.9-1.5 m), widening gradually by suckers

Flowers

Small white flowers in upright clusters in late spring to early summer, followed by berries that ripen red in autumn and may persist through winter.

Foliage

Evergreen. Finely divided, compound leaves on upright stems; new growth is often bronze or reddish, maturing green and developing red or purple tones in cool weather. Colour varies with cultivar and growing conditions.

Growth

Slow to moderate

Care needed

Medium

• Water deeply through the first growing season, allowing the surface soil to dry slightly between waterings.
• Apply 2-3 in (5-8 cm) of organic mulch, keeping it clear of the stem bases.
• In spring, top-dress with compost; use a balanced slow-release fertiliser only if growth is weak.
• Remove unwanted suckers and seedlings promptly.
• Remove flower clusters before berries develop where bird poisoning or seed spread is a concern; do not plant where locally invasive.

Pruning. In late winter or early spring, cut up to one-third of the oldest or tallest canes to ground level to encourage fresh growth from the base. Avoid shearing into a tight hedge, which spoils its layered shape.

Late winter

Thin old canes at ground level and remove dead or damaged stems.

Spring

Plant in colder regions once the soil is workable; water thoroughly and mulch.

Spring

Top-dress with compost and check around established plants for suckers and seedlings.

Late spring

Remove flower clusters if you need to prevent fruiting and seed spread.

Summer

Water during extended dry weather, especially in containers or beneath trees.

Autumn

Remove any remaining fruit before birds take it, and dispose of it securely.

• Use as a loose, upright accent beside a shaded entrance or courtyard wall where it is not invasive.
• Combine with broad-leaved camellias or azaleas for contrasting leaf texture.
• Layer behind low hellebores and Japanese forest grass in a sheltered, partly shaded border.
• Use compact selections in large containers for foliage colour, choosing verified non-fruiting plants where available.

Garden styles it suits: Japanese, Modern courtyard, Woodland, Traditional, Autumn colour and Winter interest.

Plant it with: Japanese forest grass, Hellebores, Camellias, Azaleas and Hardy geraniums.

Wildlife: Flowers attract some visiting insects, but this is not a good choice for feeding birds. Its berries contain cyanogenic compounds, and fatal poisoning has been documented in birds, particularly cedar waxwings eating large quantities.

• Root rot in waterlogged soil: improve drainage or move the plant; avoid repeatedly soaking already wet ground.
• Iron chlorosis on alkaline soil, showing as yellow leaves with greener veins: check soil pH and use an appropriate chelated iron treatment if needed.
• Scale insects on stems or leaves: inspect regularly, prune heavily infested stems and use a locally approved horticultural oil according to its label.
• Winter leaf scorch or dieback in exposed sites: provide shelter from drying winds and prune damaged growth after new shoots reveal what has survived.

Toxic to cats, dogs, horses and people if eaten. Leaves and berries contain cyanogenic compounds; ingestion can cause serious, potentially fatal poisoning, with berries a particular concern for children and animals. Contact a veterinarian or poison information service promptly after suspected ingestion.

Where it spreads. Spreads by bird-carried seed and local suckering. It is listed as invasive in parts of the southeastern and mid-Atlantic United States, including Florida, Georgia, Alabama, North Carolina and Virginia. It is also an environmental weed in parts of eastern Australia, including New South Wales and Queensland. Check local guidance and choose a non-invasive alternative where advised.

• Bamboo (Bambusoideae)

  True bamboos are grasses with jointed canes and simple, narrow leaves. Nandina has branching, divided leaves made up of many leaflets, plus conspicuous white flower clusters and red berries.

• Oregon grape (Mahonia aquifolium)

  Oregon grape has stiff, glossy leaflets with sharp, holly-like teeth, yellow flowers and blue-black berries. Nandina has smoother-edged leaflets, white flowers and red berries.

Nandina comes from the Japanese name nanten, domestica means cultivated or of the household, and heavenly bamboo refers to its bamboo-like stems and foliage.

Propagation. Divide rooted suckers in spring or take semi-ripe cuttings in summer. Seed is slow and variable, and seedlings do not reliably retain cultivar characteristics; avoid seed propagation where the plant can escape.

Accepted botanical name

Nandina domestica

In the US and Canada

Introduced in the lower 48 states and Pacific Basin.

Native range

China North-Central, China South-Central and China Southeast.

Measured

Soil pH 4.5 to 6. Average height 244 cm.
