Box honeysuckle

Sun

Full sun to partial shade; tolerates deeper shade but grows less densely.

Water

Water regularly during establishment. Once established, it tolerates short dry spells, but prolonged drought can cause leaf loss.

Soil

Most well-drained soils, including chalk, clay and sandy soil; tolerates acidic to alkaline conditions. Avoid persistently waterlogged ground.

Height

5-8 ft (1.5-2.4 m) unpruned; easily maintained lower

Spread

5-8 ft (1.5-2.4 m) unpruned

Flowers

Small, creamy-white flowers in late spring, often hidden among the leaves; clipping greatly reduces flowering.

Foliage

Evergreen. Tiny, glossy, dark-green leaves in opposite pairs on fine, densely branching stems.

Growth rate

Fast

• Water deeply during dry spells through the first growing season.
• Apply organic mulch over the root area, keeping it clear of the stems.
• Feed lightly in spring only if growth is weak or the soil is poor; excessive feeding increases trimming.
• Check soil moisture beneath dense hedges, where rain may not reach the roots.
• Keep young plants free of competing grass and weeds until established.

Pruning. Clip hedges in late spring and again in summer as needed, keeping the base slightly wider than the top; avoid trimming during extreme heat or drought. Renovate an overgrown shrub by cutting back hard in early spring after severe frosts, and check for active bird nests before any pruning.

Early spring

Remove winter-damaged shoots and renovate overgrown shrubs once severe frosts have passed.

Spring

Refresh mulch and give a light feed if growth is weak.

Late spring

Give established hedges their first shaping trim after checking for nesting birds.

Summer

Trim vigorous regrowth as needed and water young plants during dry spells.

Early autumn

Plant where winters are mild, watering thoroughly; in cold regions, wait until spring.

Winter

Brush heavy snow gently from clipped plants before branches bend or split.

• Clip into low hedges around beds or along paths for a continuous evergreen outline.
• Use for simple balls, mounds or larger topiary shapes where frequent trimming is practical.
• Plant behind flowering perennials to provide a dark-green backdrop through winter.
• Allow informal groups to arch naturally beneath open-canopied trees or along a mixed shrub border.

Garden styles it suits: Formal, Topiary garden, Tudor knot garden, English country, Modern courtyard and Winter interest.

Plant it with: Hardy geranium, Lady's mantle, Japanese anemone, Hellebore, Snowdrop and Panicle hydrangea.

Wildlife: Unclipped plants offer small flowers for visiting insects, berries for birds and dense shelter. Frequent clipping reduces flowers and fruit; established hedges may contain nesting birds.

• Sparse or bare hedge bases: trim with a wider base than top so light reaches the lower branches; renovate badly neglected plants in early spring.
• Root rot in wet ground: improve drainage or move the plant rather than continuing to water saturated soil.
• Aphids on soft shoots: wash off small colonies with water and encourage natural predators.
• Winter scorch or drought browning: shelter from drying winds, mulch the roots and water during prolonged dry weather when the ground is unfrozen.

Do not eat the berries: honeysuckle fruits can cause stomach upset, vomiting or diarrhoea. Species-specific evidence for poisoning in cats, dogs and horses is limited, so keep pets and livestock from eating the berries or substantial amounts of foliage; seek medical or veterinary advice after a significant ingestion.

Where it spreads. Naturalised and capable of invading native vegetation in New Zealand and parts of southeastern Australia, including Tasmania. Birds spread the seed, and low branches can root where they touch the soil; check local weed guidance before planting near bushland.

• Common box (Buxus sempervirens)

  Box has thicker, leathery leaves and generally slower, stiffer growth; box honeysuckle has finer, more flexible shoots and smaller, thinner leaves.

• Box-leaved holly (Ilex crenata)

  Its leaves are alternate and usually have finely scalloped edges; box honeysuckle has opposite leaves with smooth edges.

• Privet honeysuckle (Lonicera pileata)

  It generally forms a lower, spreading shrub with longer, more narrowly oblong leaves; box honeysuckle is more upright with smaller, rounded to oval leaves.

Lonicera honours the botanist Adam Lonitzer, nitida means shining or glossy, and box honeysuckle refers to its resemblance to box.

Propagation. Take semi-ripe cuttings in summer, or layer a low branch and separate it once well rooted.

Accepted botanical name

Lonicera pileata yunnanensis Lonicera nitida is an older name for Lonicera pileata yunnanensis.
