Himalayan Balsam is another weed out of control in the UK. It colonizes the banks of fresh-watercourses very easily, both rivers and canals. The weed can be removed manually by pulling, when the roots and all are extricated. But any piece of stem which includes a node left on the ground can take root again, so all bits should be removed. Any seeds are viable for only two years.
The flowers smell sickly sweet, and, according to some, the crushed stems and leaves smell like Jeyes Fluid. The seed pods, when ripe and touched, suddenly release pent-up elastic energy, catapulting the seeds out up to a distance of 12 metres. It thus readily spreads, especially beside streams where the seeds can be transported by the flowing water.
There are some saving graces to this plant: it looks nice when in flower (which is why it was imported into this country many decades ago), and the flowers attract many bees, which in recent years have been seen a drastic and worrying decline since they are the main pollinators of some flowers (and crops).
It is recounted that children used to carefully collect a handful of ripe seed pods and then squeeze them. This triggered their explosive curling and felt like a lot of wriggling squirming worms within the closed hand. The seeds, which number 5 to 10 within one pod, can be flung out at such high speed that they are thrown up to 5 metres. If they land in flowing water, they will be carried to pastures new, but always near water, for the plant likes dampish ground.
