I stopped and stared as I walked past a smart new townhouse and saw these plants growing up the wall.

At first I thought it was a mural. Then I realised they were real. This photo is of the side wall. Spray-on shrubs, perhaps. Yet they are growing too, and putting out spring shoots.

It all looked a bit unnatural and surreal to me. I was relieved to see rebel leaf tips making a break for freedom at the top of the wall. If I was a plant, I don’t think I’d be satisfied with a two-dimensional life.
