The American Horticultural Society’s highest award, the Liberty Hyde Bailey Award is given to an individual who has made significant lifetime contributions to at least three of the following horticultural fields: teaching, research, communications, plant exploration, administration, art, business, and leadership.

Named after Liberty Hyde Bailey (1858–1954), horticulturist, educator, author. First awarded in 1958.

Jim FolsomThis year’s winner of the American Horticultural Society’s highest honor, given for career achievements in multiple horticultural disciplines, is James P. Folsom of San Marino, California. Since 1987, Folsom has been Director of the Botanical Gardens at the Huntington Library, Art Museum, and Botanical Gardens, also in San Marino. He originally joined the Huntington staff in 1984 in the role of assistant curator. Folsom and his wife, Debra—who is also a botanist—raised their children Molly and Jimmy at a home on the Huntington’s grounds.

Folsom, whose colleagues call him “Jim,” oversees more than a dozen thematic gardens covering 130 acres of the Huntington’s 207-acre grounds. He serves as visionary and project head for the development of new gardens and botanical facilities and the restoration of historic gardens and maintenance. Much of his focus is directed toward educational programs that increase public interest and understanding of the science, culture, and history of plants and gardens.

He supervises some 85 staff members, including 10 curators, 40 gardeners, and numerous technicians and other staff, as well as hundreds of volunteers who maintain the botanical collections, provide interpretive programs for visitors, and propagate plants.

Huntington Chinese GardenSome of the most notable additions to the garden under Folsom’s tenure include a botanical research and education facility in 2001, the Helen and Peter Bing Children’s Garden in 2004, the Rose Hills Foundation Conservatory for Botanical Science in 2005, the Chinese garden—Liu Fang Yuan, or the Garden of Flowing Fragrance—in 2008, as well as the renovation and expansion of the Japanese Garden in 2012. As part of the Huntington’s Centennial this year, an expanded Chinese garden is opening to the public, making it one of the largest classical-style Chinese gardens in the world.

Folsom has also been instrumental in adding invaluable botanical collections to the Huntington, including, most recently, more than 5,000 orchids donated by the family of the late collector and grower S. Robert Weltz that will help the Huntington become a center for orchid conservation.

“Under Jim Folsom’s guidance, the Huntington’s gardens have achieved an uncannily perfect union of scientifically significant research collections and astonishing artistry,” says Panayoti Kelaidis, Director of Outreach at the Denver Botanic Gardens in Colorado. “Jim has fostered a vibrant culture among his staff and made his garden the envy of our profession.”

Folsom was born in what he describes as the “drop-dead gorgeous small Alabama town of Eufaula,” where he says his lifelong love of plants developed because he “grew up with astonishing freedom to roam and observe.” After high school, he attended nearby Auburn University, graduating with a bachelor’s degree in botany, before serving three years in the United States Air Force. Following his service, he went on to get a master’s degree in biology from Vanderbilt University, and then a doctorate in research botany from the University of Texas at Austin (UTA). While working on his doctorate, he spent several years as a teaching assistant in UTA’s botany department.

Folsom’s botanical and horticultural interests are wide-ranging, but his research in the 1970s and 1980s was largely focused on the orchid family. He did extensive field work in Central and South America, including stints in Costa Rica, Panama, and Peru, as well as a year in Colombia on a Fulbright Pre-Doctoral Fellowship.

Over the course of his career, Folsom authored numerous research papers, articles, and reports in both scientific and popular publications. Some of Folsom’s photos and musings on plants and gardens—including excerpts from A Botanical Reader, his free e-book on Apple—are published in a blog called botanyincontext.com, which is available on the Huntington’s website.

Folsom has been the recipient of numerous awards. He was named a Friend of the Cactus and Succulent Society of America in 1996, was awarded a Professional Citation by the American Public Gardens Association in 1999, received the Medal of Honor from the Garden Club of America in 2007, and was given the AHS’s Professional Award in 2003. In 2016, he was inducted into the Order of the Rising Sun (Gold Rays with Rosette) by the government of Japan for the Huntington’s assistance in celebrations honoring the centennial of Japan’s gift of cherry trees to the United States in 2012.


Given to an individual, organization, or program that has inspired and nurtured future horticulturists through efforts in children’s and youth gardening. Named for Jane L. Taylor, youth advocate, horticulturist, educator. First awarded in 2000.

Grow Dat Youth FarmGrow Dat Youth Farm, an urban farm and youth development organization in New Orleans, Louisiana, was founded in 2010 as a way of nurturing a diverse group of young leaders through the growing of food. The organization works to create a more just and sustainable food system in a region where many people face food insecurity. In its first year, the program employed 13 student workers who grew 2,200 pounds of food. Today, more than 250 youth leaders have graduated from the farm’s leadership programs,  and the farm is producing 25,000 pounds of food annually, 30 percent of which is donated to community partners who help distribute the food where it is needed the most. The organization’s executive director, Devon Turner, is a Louisiana native who has spent her career focused on supporting and advocating for young men and women, including as an educator teaching about social justice issues.


Recognizes exemplary contributions by an individual, institution, or company demonstrating the application and value of horticulture in creating livable communities that are greener, healthier, and more equitable. First awarded in 1985 as the Urban Beautification Award; renamed in 2019.

Blocks in BloomEstablished by the Cornell Cooperative Extension of Monroe County, Blocks in Bloom debuted in 2015 in the City of Rochester, New York. The idea was to build community, enhance property values, and promote healthy living in the city’s low-income neighborhoods by providing free plants and gardening instruction to participating residents. The program is led by Master Gardener volunteers, who train residents to prepare, plant, and maintain their front-yard flower gardens. In 2018, a leadership development component was added, enabling experienced residents to become mentors to new program participants.

The program’s success is indicated by its growth from serving two blocks with 15 households in 2015 to serving 15 blocks and 135 households in 2019. By design, the program has a sustainable structure—built around volunteers and donated materials—that makes it easily replicable in other communities.
