2. Plant Description
Peanuts are annual plants. They are usually harvested when the leaves turn to yellow. These plants need 100 to 150 frost-free days to mature.
Different varieties will have different maturity periods. Those with shorter maturity periods are more perfect for areas with cooler climates.
The peanut is a member of the pea family. Therefore, it is closely related to bean, soybean, and other legumes.
It is different from the tree nuts, such as almond and walnut since the fruit or nut is located under the ground. The scientific name of this plant is Arachis hypogaea.
Meanwhile, peanuts are also known as goobers, groundnuts, and monkey nuts.
Peanuts may be considered as a legume, but peanuts taste like tree nut. Moreover, it has hard skin and dry fruit.

Peanut leaves are small and a bit oval. Its size is about 10 mm wide. These leaves grow on small, sturdy, and hairy stems.
The height of the stem can reach up to 45 cm tall. Certain varieties have runner stems. Meanwhile, others have erect stems.
Peanuts flowers are small. They are yellow and self-fertile. These flowers will bloom when the peanut plants are about 40 days old.
Moreover, they emerge from the lower part of the stems. After the pollination occurs, these flowers will wither and peanut ovaries will start to develop.
A peg looks like a stalk which length is about 10 cm. It is also known as the budding ovary. It emerges from the base of a peanut flower.
Then, it grows toward and penetrates the soil. This ovary then will develop fruit or a peanut pod under the ground.
Peanut plants will keep flowering even though the previous flowers have pollinated and produced peanut pods.
As a result, when you harvest them, you will likely get some young peanut pods. Inside these pods, you will find 1 to 3 fruits or kernels.
Certain varieties can produce more than 3 kernels in one pod.
Moreover, different varieties also produce kernels in different sizes. The kernels are covered with a thin skin. In general, the color of this skin is white or pale pink.
