In Detail

Identification of Himalayan Balsam:

  • Reddish coloured stems
  • Common on river banks
  • Dark green lance shaped leaves with jagged edges
  • Large, brightly coloured flowers usually in variable shades of purple and pink
  • Flowers June to October
  • Grows up to 2m height
  • Dies back at end of growing season
  • Produces 2500 seeds per plant each year
  • Explosive seed pods

Himalayan Balsam plants can produce around 2500 seeds each year. The seedpods open in such a way that the seeds are thrown several metres away from the parent plant, helping the species to rapidly spread - often quoted as 20 metres in all directions per season.

Seeds can also be transported by:

  • Water - if parent plant is close to river or stream
  • Movements of contaminated soil
  • Fishermen/walkers picking up seeds on footwear
