If you google search hard enough and long enough you will find a DEFRA
.pdf file AFAIR that explains what action and against whom is to be
taken against those growing Giant Hog weed. In the case of private
individuals growing it, who refuse to remove it, a civil action may be
taken against them by the local authority.

That is if they are allowing it to be released into the wild.
