Ochroma pyramidale, commonly known as the balsa tree, is a fast-growing tropical tree native to Central and South America. It is recognized for its lightweight wood, which is often used in model building, crafts, and various lightweight applications. The tree can reach heights of up to 30 meters and has large, heart-shaped leaves. The wood of Ochroma pyramidale is notable for its low density, making it one of the lightest commercially available woods. This characteristic, along with its strength and buoyancy, makes it a popular choice for constructing rafts, canoes, and even surfboards.
