Kassinger retraces the progress of the first botanists, including Charles Darwin, who banished myths and misunderstandings and discovered that flowers have sex, leaves eat air, roots choose their food, and hormones make morning glories climb fence posts. She goes out into the world as well, visiting modern gardens, farms, and labs to discover the science behind extraordinary plants like one-ton pumpkins, truly black petunias, ferns that eat the arsenic in contaminated soil, biofuel grass that grows twelve feet tall, and the world's only photosynthesizing animal. Kassinger also introduces us to modern scientific research that offers hope for combatting climate change and alleviating world hunger. She then transfers her insights to her own garden.

Intertwining personal anecdotes, accessible science, and little-known history, A Garden of Marvels takes us on an eye-opening journey into Kassinger's garden—and yours—offering us a new appreciation of this exquisite gift of nature.
