The peanut plant sprouts from a raw peanut planted in the ground. The stem, or peg, will emerge first, followed by the leaves.
Flowers will emerge around 25 to 40 days after the peanut has been planted. These bloom for less than a day and are self-pollinating. After the flowers have wilted, a peg will emerge from each flower head.
The emerging pegs bend toward the ground and push themselves about 2 inches into the soil. The peanuts will then form underground amid the roots of the plant.
