Himalayan balsam

  • The Himalayan balsam produces a large amount of nectar, which makes it much more attractive to pollen-spreading insects than neighbouring native species.
  • Due to its large size, the Himalayan balsam outcompetes native species for light and space.
  • The rapid growth of the Himalayan balsam and its tendency to grow around water can lead to flooding and other changes in the ecosystem’s water cycle.
