Habitat:
  • Typically found in hedgerows and on waste ground
  • Occasionally found in woodland

Description:
  • Himalayan honeysuckle is a deciduous shrub growing up to two metres tall   
  • Leaves are oval in shape and grow between 5-18cm long
  • Leaves grow in opposite pairs on the stem
  • Tall, green, bamboo-like stems
  • Pale pink-purple funnel shaped flowers (10-20mm)
  • Berries (12-15 mm in size) are purple in colour when they first form but deepen in colour to become black

Origin and Worldwide Distribution:
  • Himalayan honeysuckle is native to the Himalayas
  • It is now present across France, the United Kingdom and Ireland

Impacts:
If the plant is allowed to grow unchecked, it can form dense thickets that can dominate the habitat, outcompeting native flora species.
Is it found in Northern Ireland?

How did it get here?
  • L. Formosa was originally introduced during the Victorian era, to be planted as a cover for pheasants; this is where it gets its name ‘Pheasant berry’
  • It is still widely sold in nurseries and garden centres
  • More recent spread into the ‘wild’ has occurred because of plants escaping from gardens
  • Birds can also disperse the seeds

Management/Methods for Prevention
  • Report any sightings
  • Be Plant WISE
    • Do not plant this species – plant native species instead
    • Do not take or give cuttings from wild or cultivated plants
    • Know what you are growing
    • Never collect plants from the wild
    • Safely dispose of plants and growing media
  • The spread of the plant can be kept in check by removing spent flowers before they go to seed
