The Jatoba tree (Hymenaea courbaril) is a hardwood species native to Central and South America, particularly thriving in the Amazon rainforest. Known for its dense, durable wood, the tree produces a rich reddish-brown timber that deepens in color over time, making it highly prized for flooring, furniture, and cabinetry. Renowned for its strength and resistance to wear, the Jatoba tree is a valuable resource in woodworking.

The Black Walnut tree (Juglans nigra) is a large, deciduous hardwood native to North America, particularly the eastern United States. It is renowned for its rich, dark-brown wood, prized for its strength, workability, and pleasant fragrance. The tree produces edible walnuts encased in thick green husks, which are valued for their flavor and nutritional content. Black Walnuts also play an important ecological role, providing food and habitat for wildlife. However, the tree releases a chemical called juglone from its roots and leaves, which can inhibit the growth of certain nearby plants, showcasing a unique natural adaptation.
