"Winner of the PROSE Award in Popular Science and Mathematics, Association of American Publishers" "A work of both rigor and whimsy. Advancing chronologically, its narrative curls deep into scientific and historical detail."---Siobhan Roberts, Wall Street Journal "Brilliant and lovely. . . . Filled with wondrous photographs and illustrations, this book will please, provoke and challenge what you think about nature, may you never take it for granted again."---Jeffery Payne, The Colorado Sun "This book will be interesting to both mathematicians and gardeners."---J. A. Bakal, Choice "A rewarding adventure for anyone interested in seeing how scientific understanding becomes more nuanced and complicated as a field develops."---Christian Millichap, Math Horizons "Throughout the book, the authors . . . sprinkle in bits of whimsical fun."---Erin N. Bodine, The American Mathematical Monthly "This handsome book unpicks the splendour of plant forms. . . . There are botanical wonders sprouting under all our noses, as unfurling garden ferns remind us."---Jonathan Guthrie, Financial Times "Besides being well written, beautifully illustrated, introspective, and thoughtful (even provocative), it is a clear fun-filled expression of the authors' affection for the topic - a tender admiration of botanical spirals and a clear effort to communicate this affection as well as the importance of the topic."---Karl J. Niklas, The Quarterly Review of Biology
