It’s a breathless title for a very tranquil subject. My friend took me to see his allotment on the edge of the city. The street stops, we walk through a gate and… peace. Plants of every description, some in neat little rows, others waging nature’s gentle war. Green crawling over everything man-made, dismantling us so slowly we can’t even see it. How long would it take for a jungle to grow over the lost ruins of Manchester?
