Gardening is one of the quintessential nurturing activities and yet we understand so little about it. Here, psychiatrist Sue Stuart-Smith investigates the many ways in which mind and garden can interact. Discussing Freud's obsession with flowers, case histories with her own patients, and progressive gardening programs in such places as Rikers Island prison, Stuart-Smith weaves thoughtful yet powerful examples to argue that gardening is much more important to our cognition than we have realized.
