Thieves have been pictured stealing plants from Rotten Row.
The incident occurred on Monday, 10th August.
The border is maintained by the Friends Of Rotten Row group, who put thousands of hours a year into maintaining the historic Southport street.
One member of the group said: “It is most disheartening when things like this happen after all the hard work put in by the Volunteers.”
Rotten Row boasts one of the largest herbaceous borders in the country and takes its unusual name from the Rotten Row in Hyde Park, London.
