How pecans went from ignored trees to a holiday staple – the 8,000-year history of America’s only native major nut crop
Pecan pie has become a beloved holiday staple in the United States, but the journey of the pecan nut to its current status is rich with history and cultural significance. Native to the southern U.S., pecans are not just a culinary delight; they also represent a key agricultural product, with American trees yielding around 80% of the world’s pecan crop. These versatile nuts are used in various forms, including pecan milk, butter, and oil, but they are perhaps most famously featured in the classic pecan pie. The pecan, which is technically a drupe (a type of fruit), has been enjoyed for thousands of years, initially by Native Americans who utilized them for food, medicine, and trade. The Algonquin term “pakani,” meaning “a nut too hard to crack by hand,” aptly describes the nut’s tough exterior, which has made it a staple in many Southern recipes.
Historically, pecans were largely ignored until the late 1800s, when their economic potential was recognized. The first documented planting of pecan trees occurred in New York in 1722, with George Washington himself being an early enthusiast. However, it wasn’t until the advent of grafting techniques in the 19th century that pecan cultivation truly took off. This process, which involves joining branches from quality trees to another tree’s trunk, allowed for the production of higher-quality nuts. One notable success story is that of an enslaved man named Antoine, who developed a superior pecan variety known as Centennial, first introduced to the public at the Philadelphia Centennial Exhibition in 1876. The increasing demand for pecans saw them not just as a food source but also as a profitable crop, even leading to competitive harvesting practices.
Pecan consumption surged during times of scarcity, such as the Civil War and the World Wars, when they served as a protein-rich alternative to meat. However, post-war demand fluctuated, prompting various marketing efforts, including a national recipe contest in 1924 that generated significant interest in pecan-based dishes. Over the decades, pecans have found their way into a myriad of culinary applications, from pralines to cereals, and even into space missions due to their nutritional density and long shelf life. Today, the pecan industry faces modern challenges, including debates over its pronunciation—are they “PEE-cans” or “puh-KAHNS”?—but their place at the holiday table remains secure, symbolizing both tradition and the evolution of American agriculture. As you enjoy your pecan pie this holiday season, you can appreciate the rich history and cultural significance of this delightful nut.

Pecans have a storied history in the United States. Today, American trees produce
hundreds of million of pounds
of pecans –
80% of the world’s pecan crop
. Most of that crop stays here. Pecans are used to produce pecan milk, butter and oil, but many of the nuts end up in pecan pies.
Throughout history, pecans have been overlooked, poached, cultivated and improved. As they have spread throughout the United States, they have been eaten raw and in recipes. Pecans have grown more popular over the decades, and you will probably encounter them in some form this holiday season.
I’m

in Oklahoma, a state consistently ranked fifth in pecan production, behind
Georgia, New Mexico, Arizona and Texas.
I’ll admit that I am not a fan of the taste of pecans, which leaves more for the squirrels, crows and enthusiastic pecan lovers.
The spread of pecans
The pecan is a nut
related to the hickory
. Actually, though we call them nuts, pecans are actually a type of fruit
called a drupe
. Drupes have pits, like the peach and cherry.

The pecan nuts that look like little brown footballs are actually the seed that starts inside the pecan fruit – until the fruit ripens and splits open to release the pecan. They are usually the size of your thumb, and you may need a nutcracker to open them. You can eat them raw or as part of a cooked dish.
The pecan
derives its name
from the Algonquin “pakani,” which means “a nut too hard to crack by hand.” Rich in fat and easy to transport, pecans
traveled with Native Americans
throughout what is now the southern United States. They were used for food, medicine and trade as early as 8,000 years ago.
Pecans are native to the southern United States.

Pecans are native to the southern United States, and while they had previously spread along travel and trade routes, the first documented purposeful planting of a pecan tree was in New York in 1722. Three years later, George Washington’s estate, Mount Vernon, had some planted pecans.
Washington loved pecans
, and Revolutionary War soldiers said he was constantly eating them.
Meanwhile, no one needed to plant pecans in the South, since they naturally grew along riverbanks and in groves. Pecan trees are alternate bearing: They will have a
very large crop one year
, followed by one or two very small crops. But because they naturally produced a harvest with
no input from farmers
, people did not need to actively cultivate them. Locals would harvest nuts for themselves but otherwise ignored the self-sufficient trees.
It wasn’t until the late 1800s that people in the pecan’s native range realized the pecan’s potential worth for income and trade. Harvesting pecans
became competitive
, and young boys would climb onto precarious tree branches. One girl was lifted by a hot air balloon so she could beat on the upper branches of trees and let them fall to collectors below.
Pecan poaching
was a problem in natural groves on private property.
Pecan cultivation begins
Even with so obvious a demand, cultivated orchards in the South were still rare into the 1900s. Pecan trees don’t produce
nuts for several years
after planting, so their future quality is unknown.

To guarantee quality nuts, farmers began using a technique called grafting; they’d join branches from quality trees to another pecan tree’s trunk. The first attempt at grafting pecans was in 1822, but the attempts weren’t very successful.
Grafting pecans became popular
after an enslaved man named Antoine who lived on a Louisiana plantation successfully produced large pecans with tender shells by grafting, around 1846. His pecans became the first widely available improved pecan variety.

The variety was named Centennial because it was introduced to the public 30 years later at the Philadelphia Centennial Expedition in 1876, alongside the telephone, Heinz ketchup and the right arm of the Statue of Liberty.
This technique also sped up the production process. To keep pecan quality up and produce consistent annual harvests, today’s pecan growers
shake the trees
while the nuts are still growing, until about half of the pecans fall off. This reduces the number of nuts so that the tree can put more energy into fewer pecans, which leads to better quality. Shaking also evens out the yield, so that the alternate-bearing characteristic doesn’t create a boom-bust cycle.
US pecan consumption
The French brought praline dessert with them when they immigrated to Louisiana in the early 1700s. A praline is a flat, creamy candy made with nuts, sugar, butter and cream. Their original recipe used almonds, but at the time, the only nut available in America was the pecan, so pecan pralines were born.

During the
Civil War
and world wars, Americans consumed pecans in large quantities because they were a protein-packed alternative when meat was expensive and scarce. One ounce of pecans has the same amount of protein as
2 ounces of meat
.
After the wars, pecan demand declined, resulting in millions of excess pounds at harvest. One effort to increase demand was a national pecan recipe contest in 1924. Over 21,000 submissions came from over 5,000 cooks, with
800 of them published in a book
.
Pecan consumption went up with the inclusion of pecans
in commercially prepared foods
and the start of the mail-order industry in the 1870s, as pecans can be shipped and stored at room temperature. That characteristic also put them on some
Apollo missions
. Small amounts of pecans contain many vitamins and minerals. They became commonplace in cereals, which touted their health benefits.
In 1938, the federal government published the pamphlet Nuts and How to Use Them, which touted pecans’ nutritional value and came
with recipes
. Food writers suggested using pecans as shortening because they are composed mostly of fat.
The government even put a price ceiling on pecans to encourage consumption, but consumers weren’t buying them. The government
ended up buying
the surplus pecans and integrating them into the National School Lunch Program.
Today, pecan producers use machines called tree shakers to shake pecans out of the trees.

While you are sitting around the Thanksgiving table this year, you can discuss one of the biggest controversies in the pecan industry: Are they
PEE-cans or puh-KAHNS
?
