The American groundnut is a perennial vine native to eastern North America. This legume thrives in moist, temperate climates, often found in woodlands, along stream banks, and in other damp areas. Unlike its more famous relative, the peanut, American groundnut produces edible tubers underground, resembling small potatoes, as well as edible beans in pods.
Historically, it was a vital food source for Indigenous peoples and early European settlers due to its high protein and carbohydrate content.
While not yet a major commercial crop, its potential as a sustainable, nutritious food source is gaining recognition, with interest in its cultivation for specialty markets and as a resilient alternative crop.
