Two centuries ago, when Victorian technologists were designing the most recent in transportation engineering, Japanese knotweed reverberated like a very clever idea.
A plant which is usually colonised volcanoes in Japan was imported to Britain to help hide, or perhaps even stabilise, railway embankments.
