Pecan
History

Before European settlement, pecans were widely consumed and traded by Native Americans. As a wild forage, the fruit of the previous growing season is commonly still edible when found on the ground.

Pecans first became known to Europeans in the 16th century. The first Europeans to come into contact with pecans were Spanish explorers in what is now Louisiana, Texas, and Mexico. These Spanish explorers called the pecan, nuez de la arruga, which roughly translates to "wrinkle nut". Because of their familiarity with the genus Juglans, these early explorers referred to the nuts as nogales and nueces, the Spanish terms for "walnut trees" and "fruit of the walnut". They noted the particularly thin shell and acorn-like shape of the fruit, indicating they were referring to pecans. The Spaniards took the pecan into Europe, Asia, and Africa in the 16th century.

In 1792, William Bartram reported in his botanical book, Travels, a nut tree, Juglans exalata that some botanists today argue was the American pecan tree. Still, others argue hickory, Carya ovata. Pecan trees are native to the United States, and writing about the pecan tree goes back to the nation's founders. Thomas Jefferson planted pecan trees, C. illinoinensis (Illinois nuts), in his nut orchard at his home, Monticello, in Virginia. George Washington reported in his journal that Thomas Jefferson gave him "Illinois nuts", pecans, which Washington then grew at Mount Vernon, his Virginia home.

Commercial production of pecans was slow because trees were slow to mature and bear fruit. More importantly, the trees grown from the nuts of one tree have very diverse characters. To speed nut production and retain the best tree characteristics, grafting from mature, productive trees was the apparent strategy. However, this proved technically challenging. The Centennial cultivar was the first to be successfully grafted. This was accomplished by an enslaved person called Antoine in 1846 or 1847, who was owned by Jacques Telesphore Roman of the Oak Alley Plantation near the Mississippi River. The scions were supplied by Dr. A. E. Colomb, who had unsuccessfully attempted to graft them.
