In the heart of a botanical garden in a medieval German university town stands a majestic ginkgo tree. This silent witness has observed the quiet rhythms of transformation across three human lifetimes for over a century. In 2020, a Hong Kong neuroscientist, exploring the minds of infants, initiates an unexpected experiment with the ancient tree. In 1972, a young student is profoundly changed by the simple act of observing and connecting with a geranium. In 1908, the first female university student discovers, through the lens of photography, the sacred patterns of the universe hidden in the humblest of plants. We follow their clumsy and inexplicable attempts to connect—each deeply rooted in their own present—as they are transformed by the silent, enduring, and mysterious power of nature. The ancient ginkgo brings us closer to what it means to be human: to our yearning for belonging.
