Himalayan Balsam Overview

Impatiens glandulifera is known commonly as Himalayan balsam. It is an annual weed that is incredibly fast growing, it produces an abundance of seeds that it can fling up to 7 meters, making this very invasive. Its quick growth rate and high seed dispersal mean it easily colonises river banks, which in turn increases soil erosion and flooding.
