Himalayan Balsam (Impatiens glandulifera) looks like Ontario’s native Jewelweed (Impatiens capensis), except that it is enormous! They are related species, but the Ontario version has yellow-orange flowers.
You can spot the Himalayan Balsam, as it grows very large. Like many invasive species, they overwhelm native plants, crowding out those who belong here, reducing biodiversity and the ecological value of land. Fortunately, unlike some of my other riparian plants, it isn't poisonous.
Those who warn us of it, claim that it has nectar that draws pollinators away from native species. I'm not sure how true that is, since birds and bees seem to visit a variety of species, rather than depending upon only one.

Mine is snuggled in between my Hop bines. I imagine a previous owner, all three seemed to be avid gardeners, actually made his own beer!
It is called an annual herb, and while native to the Western Himalayas, in the early 1800s it was spread, as these things are, to Europe, New Zealand, and North America by gardeners.
It's common name, Touch-me-not, derives from the way the mature seed pods explode when you touch it. It sends the seeds flying up to 5m (~5 yards) from the parent plant, producing up to 800 seeds per plant.
It is easy to get rid of the plant, as its roots are very shallow. I'm not sure how it survives, standing as tall as it does!

ControlAnnual management is required and repeat treatments must be completed. It is also important to properly dispose of plant materials through municipal landfill or incineration.
