茶树, or the tea tree, is a plant known scientifically as Camellia sinensis. It is the source of all traditional teas, including green tea, black tea, and oolong tea. The leaves of the tea tree are harvested and processed to create these beverages, which are enjoyed worldwide for their flavor and potential health benefits. The tea tree thrives in warm, humid climates and is primarily cultivated in regions like China, India, and Sri Lanka. It can grow into a large shrub or small tree, reaching heights of up to 10 meters. However, for tea production, the plants are often pruned to facilitate easier harvesting of the leaves.
