"[This] has always been a book for gardeners and cooks interested in unique flavors, colors, and history in their produce. This updated edition has been improved throughout with growing zones, advice, and new plant entries. Line art has been replaced with lush, full-color photography. Yet at the core, this book delivers on the same promise it made two decades ago: It's a comprehensive guide based on meticulous first-person research to these 300+ plants, making it a book to come back to season after season."--Page 4 of cover.
