Book excerpt: This lavishly photographed book, written and curated by internationally respected gardening author Christine Reid and shot by renowned photographer Simon Griffiths, focuses on 18 stunning gardens from around Australia situated on a natural 'frontier'-rainforest, desert, bushland, saltbush plains, a volcanic crater, the ocean's edge, a harbour. The featured gardens have been created or restored in locations where the surrounding natural landscape is as significant as the cultivated and designed elements. In its images and stories Gardens on the Edge is much about the diversity and character of the Australian continent as it about the gardens. The accompanying stories not only explore the establishment of the garden, but also reference Australian history and geography, and cover issues ranging from dealing with droughts and climate change to restoring a long-neglected kitchen garden.
