The Lather Tree, scientifically known as *Sapindus saponaria*, is a tropical tree native to the Americas and parts of Asia. It is recognized for its round, black fruits that contain natural saponins, which produce a lather when crushed and mixed with water. This property has made the tree valuable for traditional soap-making. The tree can grow up to 30 feet tall and features glossy, compound leaves. Its flowers are small and white, attracting various pollinators. The Lather Tree is often found in regions with well-drained soil and is used in landscaping for its shade and ornamental value.
