Springwatch in King’s Cross has taken on a bit of a dirt-busting theme with the appearance of “reverse graffiti” flowers. A scattering of tropical hibiscuses and stylised floral patterns mysteriously appeared in the last week or so in the paved pedstrianised zone near Regent Square and Cromer Street.

Is it an installation sanctioned and approved by the council, or a bit of virtual guerrilla gardening? One can almost picture a van pulling up and people armed with stencils and a high-pressure water hose jumping out, bombing the pavement with flowers and then driving off. Although reactions from authorities for this kind of work seem to range from: ‘oh, that’s nice, do carry on’ to Pythonesque legal threats.

The ‘Bansky’ of reverse graffiti, Moose, has sometimes taken the medium to a large scale, left. This technique of selective cleaning has become much more associated with advertising however (Moose included). So it is nice to see an example which doesn’t appear to be selling anything. The work is signed a couple of times with this logo – does anyone recognise it?

In the meantime, enjoy the patternated grime scene, while it lasts.
