What do you get when a quiet Wisconsin hybridizer dares to dream in yellow? A global sensation named 'Bartzella.' Voted the number one peony by the American Peony Society, 'Bartzella' is just one of Roger F. Anderson's groundbreaking creations that transformed the world of peony breeding. In this beautifully illustrated and accessible book, David E. Cartwright traces the dramatic journey of peonies from ancient China to Midwestern gardens and explores how Anderson rose to become a leading force in intersectional hybrids. Along the way, readers meet the legendary breeders, pivotal nurseries, and passionate personalities who shaped the modern peony. With a mix of horticultural insight, personal anecdotes, and vibrant photography, this is the first book to celebrate Anderson's remarkable legacy-and the Wisconsin roots of a flower beloved worldwide.
