Himalayan balsam

[MuswellMetro]

Thought this Himalayan Balsam was going to pass me by or at least that’s what I thought.
Just went to remove two supers of my hive and the bees going mad with half of the returning bees looking as though they have white mohicans so checked the small stream on the way back to the workshop and plenty of it at the bridge it will be interesting to see how far it extends.

i been looking for it in North London around Barnet and Enfield and it is not widespread, it has however spread down parts of the river Lea in enfield but in local river, just a few minor locations

but none near my hives, just a few bees carrying in orange pollen
