Spanish explorers may have brought the first peach pits to North America, but Indigenous communities helped the ubiquitous summer fruit really take root, according to a study led by a researcher at Penn State.
The study, published in Nature Communications, shows that Indigenous political and social networks and land use practices played key roles in the peach's adoption and dispersal across the continent, according to the researchers.
"Peaches need a lot of care by people to be productive. They need to be planted in appropriate places with a lot of sunlight and the right soil drainage, and they need to be pruned," said Jacob Holland-Lulewicz, first author and assistant professor of anthropology at Penn State. "For a long time, the narrative was that the Spanish introduced peaches and then peaches spread very quickly. The reality is way more complicated. How quickly peaches spread is very much a product of Indigenous networks and land management."
The researchers analyzed historical documents that mentioned peaches, such as the travel writings of French missionary explorer Jacques Marquette and English merchant Jonathan Dickinson. They also employed radiocarbon dating — a method that measures the decay of radioactive carbon-14 atoms in organic material — to determine the approximate ages of peach pits and other organic samples, like carbonized tree wood, from 28 archaeological sites and two regional locales where archaeologists previously recovered preserved peach pits.
The team found that peaches were likely widespread across Indigenous settlements in the interior southeast as early as the year 1620, roughly 100 years after the earliest Spanish expeditions in Florida and Georgia's Oconee Valley. The timing suggests that early Spanish settlements becoming important trade nodes within existing Indigenous networks created the necessary conditions for the spread of peaches, according to Holland-Lulewicz.
"Many narratives talk about the Spanish, or Europeans generally, arriving and then you see instantaneous changes to Indigenous histories and the spread of materials, but those initial interactions didn't cause major changes," he said. "It's not until Spanish networks and Indigenous networks become entangled 100 years later that we have the necessary conditions for the spread of peaches."
The team also identified what are possibly the earliest peaches in North America at a Muskogean farmstead in the Oconee Valley. In the 1990s, the late Penn State archaeologist James Hatch recovered peach pits from the bottom of post holes that once housed support structures for the farmstead's house. The researchers radiocarbon-dated charcoal, nuts, and corn kernels from these post holes and found that occupation at the site began between 1520 and 1550 and ended between 1530 and 1570. This timing suggests that peaches had spread to the interior southeast possibly decades before the founding of St. Augustine in 1565, according to the researchers.
