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.

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.
