The story of seeds, in a nutshell, is a tale of evolution. From the tiny sesame that we sprinkle on our bagels to the forty-five-pound double coconut borne by the coco de mer tree, seeds are a perpetual reminder of the complexity and diversity of life on earth. With An Orchard Invisible, Jonathan Silvertown presents the oft-ignored seed with the natural history it deserves, one nearly as varied and surprising as the earth’s flora itself.

Beginning with the evolution of the first seed plant from fernlike ancestors more than 360 million years ago, Silvertown carries his tale through epochs and around the globe. In a clear and engaging style, he delves into the science of seeds: How and why do some lie dormant for years on end? How did seeds evolve? The wide variety of uses that humans have developed for seeds of all sorts also receives a fascinating look, studded with examples, including foods, oils, perfumes, and pharmaceuticals. An able guide with an eye for the unusual, Silvertown is happy to take readers on unexpected—but always interesting—tangents, from Lyme disease to human color vision to the Salem witch trials. But he never lets us forget that the driving force behind the story of seeds—its theme, even—is evolution, with its irrepressible habit of stumbling upon new solutions to the challenges of life.

"I have great faith in a seed," Thoreau wrote. "Convince me that you have a seed there, and I am prepared to expect wonders." Written with a scientist’s knowledge and a gardener’s delight, An Orchard Invisible offers those wonders in a package that will be irresistible to science buffs and green thumbs alike.

In graduating from Gallaudet University, finding a job in Washington, D.C., and starting a family with her college sweetheart, Kitty Fischer tacitly abandoned the Louisiana Cajun culture that had exposed her to little more than prejudice and misery as a child. Upon discovering that she suffered from Usher syndrome (a genetic condition that causes both deafness and blindness), however, Fischer began an unlikely journey toward reclaiming her heritage. She and Cathryn Carroll tell the story of her heroic struggle and cultural odyssey in Orchid of the Bayou: A Deaf Woman Faces Blindness.

“By this time Mama knew I was ‘not right,’” Fischer says of her early childhood. “She knew the real words for ‘not right,’ too, though she never said those words. I was deaf and dumb.” Initially Fischer’s parents turned to folk healers to try and “cure” their daughter’s deafness, but an aunt’s fortunate discovery of the Louisiana School for the Deaf would rescue Fischer from misunderstanding and introduce her to sign language and Deaf culture. She weathered the school’'s experiments with oralism and soon rose to the top of her class, ultimately leaving Louisiana for the academic promise of Gallaudet.

While in college, Fischer met and married her future husband, Lance, a Jewish Deaf man from Brooklyn, New York, and each landed jobs close to their alma mater. After the birth of their first child, however, Fischer could no longer ignore her increasing tunnel vision. Doctors quickly confirmed that Fischer had Usher syndrome.

While Fischer struggled to come to terms with her condition, the high incidence of Usher syndrome among Cajun people led her to re-examine her cultural roots. “Could I still be me, Catherine Hoffpauir Fischer, had I not been born of a mix that codes for Usher syndrome?” she asks. “To some extent, the history of my people explains the constitution of my genes and the way my life has unfolded.” Today Fischer prospers, enjoying her time with family and friends and celebrating the Deaf, Cajun, Blind, and Jewish cultures that populate her life. Her lively story will resonate with anyone who recognizes the arduous journey toward claiming an identity.
