Many people are surprised to learn that peanuts grow beneath the soil and do not grow on trees like pecans or walnuts.
Sure, the peanut plant is beautiful and even makes flowers, but the peanuts we eat grow in the ground. Yellow flowers emerge around the lower portion of the plant about 40 days after planting.
As soon as the petals fall off, the remaining of the flower enlarges and grows down until penetrates the soil. When reaching the soil, “the embryo” turns horizontal to the soil surface and begins to mature taking the form of a peanut. You can watch how the peanut ovary begins to form in the second timelapse.
