I believe there's no commercially produced cinnamon in the USA--- from google--- S. America and the Caribbean.
"Cinnamon is the dried inner bark of an evergreen tree that is harvested during the rainy season when the bark is most flexible and easiest to work with. There are various evergreens belonging to the cinnamomum family that produce cinnamon, but the highest grade cinnamon is from the cinnamomum zeylanicum tree indigenous to Sri Lanka. In fact the name cinnamomum zeylanicum is derived from the former name of the island, Ceylon.
A wild cinnamon tree can grow to 65 feet (20 meters) high, but trees used for harvesting are pruned down at about 2 years of age to produce an abundance of finer bark-yielding growth called, tillering. Once the tree reaches 3 years of age it's harvested twice yearly following each rainy season.
At harvest time the shoots are cut and the leaves and twigs are removed with the rough outer bark. The shoots are then beaten to soften the tissues of the inner bark and make it easier to peel away in a complete strip. Once peeled, the bark is placed in overlapping, extended layers then rolled to form long canes or quills that are sun-dried. As the quills dry, the bark curls and becomes paper-like. These long canes are later cut into cinnamon sticks. Flakes left over from this process, called featherings are sold to make into ground cinnamon powder or to be distilled into cinnamon oil. Cinnamon trees can yield productive bark for about 45 years, after which they are replaced with a new seedling.
