Not really a guerrilla gardener, but I thought it would be nice to have some flowers under the tree between our house and next doors. I put some compost down and seeded with poppies and cornflowers. They came up nicely and had just started to flower and (I thought) look all summery. Just been outside and they are all gone - someone must have "weeded" them (although left some weeds). Guess this is par for the course and I am a wimp, but feel a bit saddened.
