This book is dedicated to Danny, Olly, and Uncle Eric, who created a magic garden during my childhood; and to Judy, Pip, and Wayne, who keep it alive today; to the scientists, naturalists, and traditional healers whose fascination with the Green Kingdom has helped me to understand many of its mysteries; to all those who dare to speak out against “conventional” farming and genetically modified plants and the poisoning of our planet; and to the glorious diversity and resilience of the plants and trees themselves.
