  • it has red-tinged stems and green leaves;
  • purplish pink flowers from June to October.

  • it will take a couple of seasons to get the weed under control;
  • balsam bashing work parties can be organised to clear the weed from woodland and riverbanks;
  • you can't dispose of Himalayan balsam in your green bin (garden waste) or take it to the tip (household recycling centre) it must be disposed of as controlled waste;
