About Bambara groundnut
Vigna subterranea, commonly known as the Bambara groundnut, is an annual legume cultivated for its edible, protein-rich seeds that develop underground. It forms a low, spreading bush with trifoliate leaves and yellow flowers, ideal for vegetable gardens or as a cover crop in warm regions. Its peculiar method of fruiting makes it a botanical curiosity and a valuable food resource.
Native range
Western sub-Saharan Africa
Care tips
It requires full sun and warm temperatures for optimal growth, preferably between 20-30°C (68-86°F). Watering should be regular but moderate, avoiding waterlogging, especially during pod formation. It prefers well-drained, sandy soils that are slightly acidic to neutral. A common mistake is insufficient space for the pods to penetrate the soil, which can significantly reduce yield.
