The stem is straight and cylindrical, with smooth, greyish-brown bark that becomes fissured with age. The leaves are lanceolate, glossy, and dark green on top, with a lighter underside. The inflorescence is a terminal panicle, bearing small, fragrant flowers. The fruit is a dark purple drupe containing a single seed.

Diagnostic Identification Features

Ceylon Cinnamon can be distinguished by its narrow, elongated leaves with a slightly hairy underside, and its fragrant, reddish-brown bark that peels in thin layers. The leaves are opposite and have a distinct, aromatic scent when crushed. It differs from other cinnamon species like Cassia by its lighter color and more delicate aroma.

Phenology and Growth Cycle

Ceylon Cinnamon blooms in spring, typically between March and May, depending on regional climate. Seed formation occurs in late summer to early autumn, around August to October. Harvesting is done during the dry season, usually between November and February, when the bark is most aromatic and contains the highest concentration of essential oils.
