I've seen it growing in various places around East London - front gardens, public gardens by bus stops etc.
No interactions present.
It looks like they plan to dig out the plant and the underlying earth. The site needs to be monitored for several years to deal with any surviving fragments.
You can always identify landfill sites where they haven't followed the guidelines to bury it at least 2m from the ultimate upper level: they have a fine crop of the stuff!
What do you think about the trial in progress to release this alien natural predator of the plant?
but it is to be hoped it will prove effective.
