Teak (Tectona grandis) is a tropical hardwood tree species native to mixed hardwood forests, known for its durable and water resistant wood. It is a large, deciduous tree that produces small, fragrant white flowers in dense clusters, and has large, papery leaves that are often hairy on the lower surface. The wood is highly valued for uses such as boat building, exterior construction, furniture, and other projects due to its leather-like smell and resistance to water damage.
