It may look pretty, but Himalayan balsam is an alien invader!
This invasive, non-native plant was brought to the UK in the nineteenth century, but, transplanted from its native home in the Himalaya, without other native plants to keep it in check, it has literally spread like wildlife!
This is bad news for Eden’s rivers as Himalayan balsam outcompetes our native plants, threatening their survival and destabilises riverbanks when it dies back in winter. We have made it our mission to stamp out this alien invader with our annual Big Balsam Bash month in July that everyone can get involved with, plus lots of other volunteer balsam bashing events throughout the Eden catchment.
