Nothing wrong with being a weed - they get a bad press. Weeds are actually very strong, resilient, persistant and extremely difficult to get rid of. They are the toughest of all in their group, and certainly not the wimps that their generic name has been adopted to suggest.
The only thing that makes them weeds is the fact they're not wanted where they are. To suggest that Mince is a weed is therefore entirely inaccur... oh, no... wait a minute..........
