The question of whether peanuts are classified as peas or nuts often leads to confusion. In botanical terms, peanuts are not nuts but legumes, which places them in the same family as peas, beans, and lentils. This classification arises from their growth process: peanuts develop underground in pods, unlike true nuts that grow on trees 1 3.
Understanding the Classification
- Legumes vs. Nuts:
- Legumes: These are plants that produce seeds in pods. Peanuts (scientific name Arachis hypogaea) fall into this category, sharing traits with other legumes like lentils and chickpeas.
- Nuts: True nuts, such as walnuts and almonds, have a hard shell and are typically found above ground. They are classified as drupes, which have a fleshy outer layer surrounding a hard shell that contains the seed 1 2.
- Geocarpy: An interesting aspect of peanuts is their unique growth method known as geocarpy. After flowering above ground, the plant’s stems elongate and bend down into the soil, where the peanuts develop 1.
