AHS Book Awards


Each year, the American Horticultural Society (AHS) celebrates great gardening literature.

Nominations for the Book Awards are accepted each fall.

Check out the winners of the 2021 AHS Book Award and the committee’s top choices below.

Evolution of the Annual Book Award Program


The American Horticultural Society honors outstanding garden-related books published in North America through its annual Book Award Program, which began with a list of 75 Great American Garden Books as part of the Society’s celebration of its 75th anniversary in 1997. Each year since then, a distinguished committee of garden communicators selects the award recipients from among the year’s new books submitted by publishers. Books are judged on qualities such as writing style, authority, accuracy, and physical quality. Because of this focus on the overall quality of the winning books, the award is presented jointly to the author and publisher of each book.

Nominations are accepted for the AHS Book Awards each fall. 

The Complete Book of Ferns

by Mobee Weinstein. Cool Springs Press.

Mobee Weinstein, foreman of gardeners for outdoor gardens at the New York Botanical Garden, offers readers an in-depth, yet not overwhelming, ode to the fern. Within its pages are sections on the history of the fern, botany, growing techniques, profiles of 70 different varieties, and even fern projects. Judge Amy Campion appreciated that the book includes both indoor and outdoor ferns contributing to its appeal to gardeners and houseplant aficionados alike. The judges were impressed by the beautiful photographs throughout; Viveka Neveln noted that making a book visually appealing when the plant photographs are mostly green is no small feat.


Plant Partners: Science-Based Companion Planting Strategies for the Vegetable Garden

by Jessica Walliser. Storey Publishing.

Bringing science-based evidence to the lore and old wives’ tales, author Jessica Walliser brings a fresh approach to companion planting and eye-opening information about plant interactions above and underground. Susan Eubank, judge and botanical librarian, declared that the book, “made me happy” because of its practicality and ease of use. Kim Toscano Holmes commended the author for taking the time to “compile all the research and put it together in a really great package.” She has found that there is a growing interest in this topic and feels comfortable pointing people to an evidence-based resource.
