Himalayan Balsam
by Judith Wallen and Janet Antrobus, South Cumbria Rivers Trust - 2009
The Problem
- Himalayan Balsam was introduced to England in 1839. It has colonised river banks and other damp areas, suppressing our native grasses and flowers.
- It is a brilliant reproducer and is spreading fast, forming dense stands. When the plants die back in autumn, large areas of bare soil are left, leaving banks liable to erosion. Bees love it and neglect our native English flowers!
- Himalayan Balsam has been identified by UK Plant Life as one of the top 20 most invasive species threatening our native flora.
