Within our concrete jungles resilient plants find distinctive cracks in walls and paths to thrive, inhabiting our most neglected spaces. They play a valuable role in the urban ecosystem creating diverse habitats that can result in a richer flora than a comparable area in the countryside. These rebel plants rank very highly for the quantity of their nectar and pollen, often much higher than a variety of garden plants and provide important winter food sources for native insects. Below the cracks, in the root systems, further tiny microhabitats provide a food source for birds and hedgehogs. Wild Things unearths this overlooked urban ecology and questions societal perceptions of weeds and the stigmas that surround them. Reframing this beneficial amenity can offer a fresh perspective on how cities perform and encourages debate about the value of wild urban plants.
