Charis welcomes  Beronda L. Montgomery in conversation with Colah B. Tawkin for a celebration of When Trees Testify: Science, Wisdom, History, and America’s Black Botanical Legacy, a stunning cultural and personal reclamation of Black history and Black botanical mastery that offers lessons from the natural world shared through the stories of long-lived trees.

The histories of trees in America are also the histories of Black Americans. Pecan trees were domesticated by an enslaved African named Antoine; sycamore trees were both havens and signposts for people trying to escape enslavement; poplar trees are historically associated with lynching; and willow bark has offered the gift of medicine. These trees, and others, testify not only to the complexity of the Black American narrative but also to a heritage of Black botanical expertise that, like Native American traditions, predates the United States entirely.

In When Trees Testify, award-winning plant biologist Beronda L. Montgomery explores the ways seven trees—as well as the cotton shrub—are intertwined with Black history and culture. She reveals how knowledge surrounding these trees has shaped America since the very beginning. As Montgomery shows, trees are material witnesses to the lives of enslaved Africans and their descendants.

Combining the wisdom of science and history with stories from her own path to botany, Montgomery talks to majestic trees, and in this unique and compelling narrative, they answer.

Beronda L. Montgomery, PhD, is a writer, researcher, and scholar who pursues a common theme of understanding how individuals perceive, respond to, and are impacted by the environments in which they exist. Her primary laboratory-based research has been focused on the responses of photosynthetic organisms (i.e., plants and cyanobacteria) to external light cues. Additionally, Beronda pursues this theme in the context of effective mentoring and leadership of individuals, and the role of innovative leaders in supporting success.

Beronda is author of two books When Trees Testify: Science, Wisdom, History, and America’s Black Botanical Legacy (2026, Henry Holt and Co.) and Lessons From Plants (2021, Harvard University Press).

Colah B. Tawkin is the creator and host of the internationally acclaimed Black in the Garden podcast, distributed by the NPR podcast network. Her work amplifies Black voices in gardening, agriculture, and land stewardship to a global audience.

With over five years producing more than 150 episodes, Colah has collaborated with the Smithsonian Gardens, the National Museum of African American History and Culture, and Atlanta Botanical Garden. She was commissioned by the Atlanta History Center to create The Botanical Black History series, exploring the cultural landscapes of Black America through stories that blend history, horticulture, and heritage.

As founder of Underground Arborist 501(c)3, Colah works to diversify plant-related industries while inspiring audiences to see themselves as vital stewards of their own stories—and the natural world that has always held them.
