When the Strathclyde Passenger Transport Executive decided to display artificial flowers at their 15 Underground stations in Glasgow, it was probably a matter of little consequence to most commuters.
But nine Green Party candidates who were standing in the district elections in the city launched a successful protest.
They contacted SPTE, urging them to throw out the plastic plants and replace them with the real thing.
The SPTE pondered the question then declared that real flowers, not plastic ones, would henceforth go on show at three stations - Kelvinbridge, Shields Road and Cessnock.
