The term 'bay tree' is a common name for the evergreen shrub known as Laurus nobilis, which is native to the Mediterranean region. It is an aromatic plant with glossy, dark green leaves and small yellow flowers. The leaves are often used in cooking and the wood is used for making furniture and musical instruments. The term 'LAUREL' is also used to refer to this plant, as it was historically used to make wreaths for victorious athletes and generals in Ancient Greece.
