Groundnut, commonly known as peanut, is a warm-season legume grown for its nutritious underground pods. The plant features green compound leaves and small yellow flowers. One of its unique characteristics is that after flowering, the flower stalk grows downward into the soil, where the peanut pods develop. Groundnut plants are suitable for vegetable gardens, agricultural fields, and home gardening projects with warm temperatures and well-drained soil.
Produces edible peanut pods beneath the soil after flowering and the development of underground pegs.

Find helpful answers about planting groundnut seeds, underground peanut development, and harvesting.
Plant healthy groundnut seeds in loose, well-drained soil approximately 1.5–2 inches deep. Choose a sunny location and maintain consistent soil moisture. Groundnut plants develop yellow flowers, followed by pegs that enter the soil and produce underground peanut pods. Use a sufficiently deep container if growing them in pots.
Groundnuts have a distinctive reproductive process. After pollination, the flower stalk develops into a structure called a peg, which bends downward and enters the soil. The fertilized ovary at its tip develops into an underground pod containing the peanuts. This process is known as pegging.
Groundnuts are generally ready for harvesting approximately 90–150 days after planting, depending on the variety. Check a few underground pods for mature, well-developed kernels and characteristic markings inside the shell. When enough pods have matured, carefully loosen the soil and lift the entire plant to collect the groundnuts.
