When Amy Stewart discovered a community of tree collectors, she expected to meet horticultural fanatics driven to plant every species of oak or maple. But she also discovered that the urge to collect trees springs from deeper, more profound motives, such as a longing for community, a vision for the future, or a path to healing and reconciliation. In this slyly humorous, informative, often poignant volume, Stewart brings us fifty captivating stories of people who spend their lives in pursuit of rare and wonderful trees and are transformed in the process. Vivian Keh has forged a connection to her Korean elders through her persimmon orchard. The former poet laureate W. S. Merwin planted a tree almost every day for more than three decades, until he had turned a barren estate into a palm sanctuary. And Joe Hamilton cultivates pines on land passed down to him by his once-enslaved great-grandfather, building a legacy for the future. Stewart populates this lively compendium with her own watercolour portraits of these extraordinary people and their trees, side trips to investigate famous tree collections, arboreal glossaries, and even tips for 'unauthorised' forestry. This book is a stunning tribute to a devoted group of nature lovers making their lives - and the world - more beautiful, one tree at a time.
