A French-language guide to the collections of the Arboretum national de Chèvreloup, this volume uses eighty trees as stops on a botanical journey through the grounds. It presents the arboretum as a living map of tree diversity, bringing together species from different regions and climates in a single cultivated landscape. Produced by the institution itself, the book is designed to support visitors while also offering a concise introduction to tree identification, origins, characteristics, and horticultural context. Its focus is educational and practical, helping readers understand how the arboretum organizes its collections and why each tree matters within the broader story of global plant life.
