Himalayan Balsam (Impatiens glandulifera)


Himalayan Balsam – The Problem:

Himalayan Balsam (Impatiens glandulifera) is recognised by the Environment Agency within their published hit list of “top ten invasive species marked for containment and removal". The plant has adapted successfully to UK conditions and now out-competes many native British plants, colonising whole watercourses. The plants leave watercourses vulnerable to erosion when river levels rise in winter, increasing incidences of flooding. Plants will also colonise urban areas, dominating garden lawns and causing costly delays to development sites.
