Are peanuts peas or nuts? It’s a question that’s likely crossed your mind while munching on a handful of these tasty snacks or spreading peanut butter on your morning toast. At first glance, the name “peanut” suggests it’s a nut, but the truth is a bit more complicated—and fascinating! Let’s dig into the science, history, and fun facts about peanuts to clear up the confusion once and for all.

Peanuts: A Botanical Breakdown
Despite their name, peanuts are not nuts—they’re legumes. Botanically speaking, peanuts (scientifically known as Arachis hypogaea) belong to the same family as beans, lentils, and peas. This family, called Fabaceae, is known for plants that produce pods with seeds inside. Unlike true nuts, which grow on trees and have a hard shell (think almonds or walnuts), peanuts grow underground in soft, fibrous pods, much like peas.
So why the nutty confusion? The “nut” in peanut comes from its culinary use and flavor profile. Peanuts have a rich, nutty taste and are used in recipes like homemade peanut butter or roasted snacks, which makes people associate them with tree nuts. But botanically, they’re closer cousins to chickpeas than cashews!
What Makes a Legume Different?
Legumes are plants that produce seeds in pods and have a unique ability to “fix” nitrogen in the soil, making them great for sustainable farming. Peanuts grow underground (hence the alternate name “groundnut”), and each pod typically contains 2–3 seeds, which we call peanuts. This underground growth sets them apart from peas, which grow above ground in green pods, but both are legumes with similar pod structures.

A Brief History of Peanuts
Peanuts have a rich history that spans thousands of years. Originating in South America, they were cultivated as early as 1500 BCE in Peru. Spanish explorers brought peanuts to Europe, and from there, they spread to Africa and Asia. Today, peanuts are a global staple, especially in the U.S., where they’re a key ingredient in everything from peanut butter to ballpark snacks.
Did you know the U.S. produces about 7% of the world’s peanuts, with Georgia leading as the “Peanut State”? For more fun food facts, explore our post on America’s favorite snacks.

Peanuts vs. Tree Nuts: Culinary Differences
In the kitchen, peanuts and tree nuts like almonds or pecans are often used interchangeably, but there are differences. Peanuts have a softer texture when roasted and a more pronounced earthy flavor. Tree nuts, like walnuts, tend to be crunchier and have distinct flavor profiles. If you’re wondering how to substitute them, our guide to nuts in baking can help.

Growing Your Own Peanuts
Believe it or not, peanuts are easy to grow at home if you have a warm climate and sandy soil. They need about 120–150 days of warm weather and well-drained soil. After planting, the plants produce yellow flowers, and the “pegs” (stems) burrow into the ground to form peanut pods. Harvest when the leaves turn yellow, and you’ve got fresh peanuts!
