Cinnamomum zeylanicum is an evergreen shrub/tree that grows shoots with a brown-orange outer-bark, and a bright clay-orange inner bark that dries down to a red/brown molasses color. These trees can grow upwards of 50 feet tall, but are usually kept at smaller and more manageable sizes for cultivation purposes. The leather-like leaves grow in an alternate, rosette pattern, and are ovate with pinnate venation that is visible to the eye. The fruit grows as a drupe, and the clusters of yellow/green flowers have an overall unpleasant smell. Native to Sri Lanaka, cinnamon is currently cultivated in South America, the West Indies and Myanmar.
