Pine needles are the long, slender leaves of pine trees, which belong to the Pinaceae family. They are typically green and can vary in length depending on the species of pine. Pine needles are known for their needle-like shape and are often grouped in clusters. They play a crucial role in photosynthesis, helping the tree convert sunlight into energy. In addition to their ecological importance, pine needles are used in various applications. They can be used as mulch in gardens, providing insulation and moisture retention for soil. Some cultures also use pine needles to make tea, which is rich in vitamin C and has a unique flavor.
