In Search of Thoreau’s Flowers: An Exploration of Change and Loss

Now on view at the The Gregg Museum of Art & Design, September 2025 — January 2026

about the exhibit

In Search of Thoreau’s Flowers: An Exploration of Change and Loss is an immersive multidisciplinary exhibition that marries art, science, and the humanities through a modern artistic interpretation of Henry David Thoreau’s preserved plants. The installation considers the impacts of climate change on plants around Walden Pond over the arc of one-hundred-and-twenty years. The exhibition opened at the Harvard Museum of Natural History in May 2022 and remained on display through May 2024. The core of the show is either digital or replicable (outside of Thoreau’s original specimens, which cannot travel); we welcome inquiries about bringing the installation to other institutions.

Thoreau was an enthusiastic collector of botanical samples, which document the world before the intensification of human influence on plant communities and indicate how the biosphere is responding to climate change. We draw upon 648 of of Thoreau’s pressed plant (‘herbarium’) specimens preserved in the Harvard University Herbaria. The digitization of these specimens have expanded access beyond the scientific community to humanities scholars, citizen scientists, and artists, in turn facilitating creative partnerships such as that which fueled the current exhibit.

An estimated 30% of plant species from Thoreau’s records have gone locally extinct, and another 35% are close to extinction, in large part due to human-driven changes in the environment. Thoreau’s collection is a botanical time machine that exists in combination with the naturalist’s notes about when and where his specimens were collected. Our installation draws attention to plant responses to environmental change through cyanotypes, data visualization, soundscapes, and spatial augmented reality.

In Search of Thoreau’s Flowers invites visitors to experience emotionally resonant connections to the profound loss of natural diversity caused by human-induced climate change. It urges us to reflect on the beauty of the natural world, calling attention to our collective need to protect and restore it.
