After the Alberta at Noon phone in show on CBC radio Philip Mees followed up with this comment today:
You mentioned ‘touch me not’ on CBC’s Wildrose today. I think that that’s the same as Himalayan balsam or Impatiens glandulifera. According to an article in the summer issue of Gardener for the Prairies this plant is a now listed as a prohibited weed in Alberta.
Of course Philip is correct - sorry I sloppily used the common name. You can google Impatiens glandulifera to see photos.
