Groundnuts/Peanuts Leaves, also known as peanuts, are a legume crop widely cultivated for their seeds, which develop underground, and their above-ground leaves. The leaves of the groundnut plant have several distinct characteristics:

Groundnut leaves are compound leaves, meaning each leaf is composed of multiple leaflets. Typically, there are four leaflets per leaf, arranged in pairs opposite each other, with an odd one at the tip.

The individual leaflets are oval or lance-shaped, with a pointed tip and a slightly serrated (toothed) edge.

The color of groundnut leaves varies depending on the specific variety and growing conditions. They are generally a bright green shade, but the intensity can differ based on factors such as sunlight exposure and soil nutrients.

The leaves are arranged alternately along the stem, meaning that each leaf emerges from a different point on the stem in an alternating pattern.

Groundnut leaves can vary in size, with mature leaves usually ranging from 2 to 5 inches (5 to 12 centimeters) in length and 1 to 2 inches (2.5 to 5 centimeters) in width.

The leaves have a relatively smooth texture, and the surface is covered in fine hairs or trichomes, which can give them a slightly fuzzy appearance.

ike other plant leaves, groundnut leaves play a crucial role in photosynthesis. They contain chlorophyll, a pigment that captures sunlight to convert carbon dioxide and water into energy-rich sugars, which the plant uses for growth and development.

While groundnut leaves are primarily valued for their seeds, the leaves are not commonly consumed by humans. However, they can be used as animal fodder or added to compost to enrich the soil.

It’s worth noting that groundnut leaves are not commonly featured or sought after in culinary applications. Instead, it is the seeds (peanuts) that are widely used in various culinary preparations, oils, and snacks worldwide.
