Tectona grandis reaching heights of 50 m, is a deciduous timber tree belonging to the Verbena family. Originally it came from India, but it can also be found from Myanmar to Laos and is nowadays being harvested on plantations in West Africa and Indonesia. The very big elliptical leaves can reach 75 cm. The small blue or white blossoms with 5 or 6 petals form terminal panicles. The fruit contains kernels. The bright yellow to brown coloured wood floats on water when dried. Due to its longevity and hardness Teak is sought-after in shipbuilding, construction of bridges and laying of floors.
Furthermore it is a wood much sought-after for furniture. Teak is resistant to infestation by insects and to weathering. Teak garden furniture can be left outside throughout the year. After several years in the open it will turn a characteristic grey. Teak derives its exceptional quality from the silicate stored in its cells that sort of petrifies them. Also, the wood turns waterproof because it contains a small quantity of rubber.
