Invasive Non-native Species

Himalayan Balsam Impatiens glandulifera

Introduced as a garden plant in the early 19th century Himalayan Balsam, Impatiens glandulifera, was first recorded in the wild in 1855 and is now common throughout the UK.

It has explosive seed heads and the small seeds are easily dispersed by wind or water. It is very invasive, spreads rapidly suppressing native plant growth and it can cause erosion on river banks
