Which plant is the source of the spice cinnamon, especially the bark of Cinnamomum verum?

Cinnamomum verum is a major source of cinnamon, especially the type often called Ceylon cinnamon.

Cinnamomum verum is an evergreen tree in the laurel family, Lauraceae, native to Sri Lanka and parts of southern India. Cinnamon is made from inner bark. When young branches are harvested, the outer bark is removed and the inner bark is processed; as it dries, it curls into familiar quills.

Ceylon cinnamon is often called “true cinnamon,” although that name can oversimplify the broader cinnamon trade. Several related Cinnamomum species are also used, including Cinnamomum cassia, commonly sold as cassia or Chinese cinnamon. They differ in flavor, appearance, and typical coumarin content.

Cinnamomum verum leaves and bark are aromatic because they contain volatile oils. The tree is also grown ornamentally in warm climates, but its commercial importance comes chiefly from spice production.
