The American Garden (noun) as an artform is a long conversation between ecosystem, colonialism, migration, and the cross-pollination of ideas. American Gardening (verb) reflects a reciprocal relationship with the natural world: we need nature, but more importantly, nature needs us.
Unknown Studio was thrilled to explore these themes through our installatino The Ghost Forest at the Pennsylvania Horticultural Society’s 2026 Philadelphia Flower Show. This year’s theme, Rooted: Origins of American Gardening, coincides with the nation’s 250th birthday.
A void represents where the American Chestnut once grew. A keystone within the eastern woodland, the Chestnut was at once interconnected with and sustaining of human life. Our exhibition invites the public to contemplate loss, while illuminating the beauty of a future woodland through partnership with the gardener.
Unknown Studio actively engaged in work on-the-ground. Our collective gathering of acorns, chestnuts, locust pods, hickory nuts, and magnolia cones over the course of months yielded time to contemplate the questions guiding this installation:
How do we fill the vast ecological niche of the American Chestnut while staying true to the native plant community of the eastern seaboard?
How do we preserve the cultural meaning of the Chestnut without losing hope of its return? Is this a productive form of nostalgia?
Is something better than nothing?
Does a simple act of small-scale gardening make up for ecological and cultural loss?
Passive ecological regeneration is impossible; restoring the woodland and tending the forest floor will take stewardship in the smallest and broadest sense. The chestnut seedlings within our Garden are entirely American Chestnuts from two mother trees in Cumberland County, PA. That they live at all is the result of the persistence of people and the protection of their roots.
Gratitude to for the opportunity, to for seedlings, to for advice, to for extra hands, to for prunings, to for the tools, and to our families & neighbors for the nuts
