cinnamon plant saigon cinnamon plant Cinnamomum loureiroi Nees Saigon cinnamon (*Cinnamomum loureiroi*, also known as Vietnamese cinnamon or Vietnamese cassia) is an evergreen tree indigenous to mainland Southeast Asia. Despite its name, Saigon cinnamon is more closely related to cassia (*C. cassia*) than to cinnamon (*C. verum*, "true cinnamon", Ceylon cinnamon), though in the same genus as both. Saigon cinnamon is used primarily for its aromatic bark, which has a taste quite similar to that of *C. cassia*, but with a more pronounced and complex aroma.
