Glossy abelia

Abelia × grandiflora

In other languages: Abelia (Nederlands) · Abélia à grandes fleurs (Français)

Abelia × grandiflora is a semi-evergreen shrub, a garden hybrid of two Chinese abelias. From July into October it carries small clusters of lightly scented bells, white flushed with pink, which attract bees and butterflies. Its graceful, arching branches with glossy leaves form a loose, elegant shrub of about 1.5 m. After flowering, the pink to bronze sepals stay on for weeks, so it gives colour until late in autumn. There are also variegated varieties, such as ‘Francis Mason’, with yellow-edged leaves.

In your garden

Why grow it?

  • Flowers late and long, from July into October, when many shrubs have finished.
  • A valuable late source of nectar for bees, bumblebees and butterflies.
  • The flowers have a light, sweet scent.
  • Semi-evergreen: in mild winters it keeps much of its foliage.
  • Fits into a mixed border, an informal hedge or a large pot.

Glossy abelia: where does it grow best?

  • Sun or light partial shade; it flowers most freely in sun.
  • A warm, sheltered spot, out of cold east winds.
  • Well-drained, humus-rich soil: sand, loam or clay, acid to neutral, not too dry.
  • Space 1–1.5 m apart; for an informal hedge about 80 cm.

Goes well with

  • Michaelmas daisy: Flowers at the same time in September–October and also attracts butterflies.
  • Ornamental grasses: Airy stems beside the arching branches.
  • Lavender: A fragrant blue base in summer.
  • Sedum: Flat flower heads in autumn, just as popular with bees.

Maintenance

Glossy abelia: when and how to plant it?

Plant in April–May and September–October.

  1. Plant in April–May or September–October.
  2. Dig a hole twice as wide as the root ball and mix in compost.
  3. Set the shrub at the same depth as it was in the pot and firm the soil well.
  4. Water in well and mulch the base with compost or wood chips.
  5. Water regularly during the first year.

Care

Water
Regularly in the first year; after that only in long dry spells.
Feeding
A layer of compost or a little organic feed in spring.
Mulching
In autumn, a mulch around the base as protection against frost.
Pot
In a large pot with compost for shrubs; water regularly in summer.

Tip: Plant it in a sunny, sheltered spot. Prune lightly in April and remove a few old stems at the base: it flowers on new wood into autumn.

Glossy abelia: when to prune it?

Pruning months: April.

When: In April, once the worst frosts are over: it flowers on new wood.

How:

  • Cut frosted shoot tips back to healthy wood.
  • Each year, remove a few of the oldest stems at the base; young shoots will take their place.
  • Shorten over-long branches a little, but keep the arching shape.
  • A neglected shrub can be cut back hard in April: it usually regrows well.

Caution: Don’t clip it into a tight ball: it will lose its graceful shape and flower less.

Pruning: when and how · Pruning calendar and basic rules

Propagation

Softwood cuttings
In June–July, 8–10 cm cuttings from non-flowering shoots, under a plastic bag.
Semi-ripe cuttings
In August, 10 cm cuttings in a cold frame or under plastic. Overwinter them frost-free.

Glossy abelia: how does it get through the winter?

Hardy to −15 °C: protect young plants.

  • Hardy to about −15 °C: in cold winters it loses many leaves and the shoots can die back.
  • It usually regrows in spring, if need be from the base.
  • Mulch the base in autumn with compost or leaf mould.
  • In a pot: stand it against a wall and wrap the pot.

Diseases and pests

  • Frost damage: Dead shoot tips after a severe winter. Cut them back to healthy wood in April.
  • Aphids: Sometimes on the young shoots. Spray them off with water.
  • Few flowers: Too much shade, or pruned in summer. Give it a sunny spot and prune only in spring.
  • Limp leaves: Drought, especially in a pot. Water generously.

Through the year

  • April: Prune: remove frosted tips and a few old stems. Plant.
  • May: Plant. Give compost.
  • June: Take softwood cuttings.
  • July: First flowers.
  • August: In flower and full of bees and butterflies. Take semi-ripe cuttings. Water in dry spells.
  • September: In flower. Plant.
  • October: Last flowers and pink sepals. Plant. Mulch.
  • November: Top up the mulch around the base.
