Milan has a wealth of greenery: besides the central parks, one can admire tree-lined streets, squares, little gardens and playgrounds almost everywhere. The aim of the book is to help us observe plants in a different way: their shapes, branching, and annual growth are the response of vegetable organisms to the stimulations and stresses of their environment. An in-depth knowledge of Milan’s vegetable heritage can help both ordinary citizens and those in public administration to acquire greater sensitivity towards nature in the city and to support an environmental policy which is more focused on urban greenery.
