Spotted laurel

Aucuba japonica · also: Japanese laurel, Aucuba

Spotted laurel is a tough evergreen shrub of 1.5–3 m for shade. It has large, glossy leaves, speckled with yellow in many garden forms, on thick green twigs. Male and female flowers grow on separate plants: only female plants bear glossy red berries in winter, and then only with a male nearby. It grows even in deep shade under trees and in dark town gardens. The berries and leaves are poisonous.

Caution: The berries and leaves are poisonous: they can cause stomach ache, vomiting and diarrhoea. Keep young children and pets away from the red berries.

In your garden

Why grow it?

  • Grows in deep shade, where little else will grow, even under trees.
  • Evergreen, with yellow-speckled leaves that brighten a dark corner.
  • Red berries all winter on female plants.
  • Tough: tolerates town air, dry shade and little care.

Spotted laurel: where does it grow best?

  • Partial to deep shade; in full sun the leaves scorch.
  • Any free-draining soil, acid or chalky; no wet feet.
  • Copes with dry shade under trees and the sheltered, dark corner of a town garden.
  • Allow 2 m width.

Maintenance

Spotted laurel: when and how to plant it?

  1. Plant in spring (April–May) or early autumn (September–October), root-balled or from a pot.
  2. For berries, plant a female with a male nearby, or choose a variety that bears berries on its own, such as ‘Rozannie’.
  3. Dig a generous planting hole and mix in a little compost.
  4. Water generously after planting and in dry spells during the first year.

Care

Watering
In dry spells during the first year; after that rarely needed, except in a pot.
Feeding
A little compost in spring.
Mulch
A layer of leaf mould keeps the soil under trees moist.
Berries
Leave them: they colour the shrub all winter, but keep an eye on small children.

Tip: A variegated spotted laurel lights up a dark corner like a lamp: put it against a wall in the shade or under trees, not in the sun.

Spotted laurel: when to prune it?

Pruning months: April–May.

When: In April–May.

How:

  • Cut overlong branches back with secateurs to just above a leaf: leaves cut through with hedge shears turn brown at the edges.
  • A shrub that has grown too big or bare can be cut back hard; it sprouts again from old wood.
  • Prune female plants sparingly: every branch you remove will bear no more berries.

Caution: April–May falls in the nesting season: check for nesting birds in the shrub before you prune.

Pruning: when and how · Pruning calendar and basic rules

Propagation

Cuttings
Semi-ripe cuttings of 10–15 cm root readily in late summer in a pot under glass or plastic. A cutting is male or female, like its parent plant.

Spotted laurel: how does it get through the winter?

Hardy throughout Belgium: no protection needed.

  • Hardy in Belgium and the Netherlands.
  • In hard frost, leaves and shoot tips may turn black; cut them off in April and the shrub will sprout again.
  • On female plants the red berries last all winter.

Diseases and pests

  • Scorched leaves: Brown or black patches on the leaves in full sun. Move it to a shadier spot.
  • Black shoot tips: After hard frost or on wet soil, shoot tips and leaves turn black. Cut them off and make sure the soil drains well.
  • No berries: Only female plants bear berries, and then only with a male nearby.

Through the year

  • January: Red berries on female plants.
  • March: Flowering: small purplish-brown flowers.
  • April: Prune; cut off frost damage; plant.
  • May: Last pruning month; plant.
  • August: Take semi-ripe cuttings.
  • September: Plant root-balled or pot-grown plants.
  • November: The berries turn red.

Use

What can you use it for?

Garden and landscape
Tough evergreen shrub for deep shade, even under trees and in town gardens.

Caution: The berries and leaves are poisonous.

You and this species

Did you know?

  • The first shrubs in Europe were all female and never bore berries; only when plant hunter Robert Fortune brought male plants from Japan around 1860 did the red berries appear.
  • In the 19th century it became a favourite of town gardens: it put up with soot, smoke and shade.
