True Cinnamon

This tree favors a warm, humid climate and grows best in full sun to partial shade, with young plants benefiting from afternoon shade until they mature and can tolerate stronger sun. It adapts to clay, loam, or sandy soils that are acidic to neutral and kept moist with good drainage, and it is propagated from seed or stem cuttings, whether direct-sown or transplanted, needing 12 to 60 feet of space depending on planting context.

Growers outside the tropics can overwinter it under glass or in a conservatory, but must reintroduce it to outdoor conditions gradually, since sudden exposure to full sun after indoor shelter can scorch the leaves. Flowering occurs in winter and relies on insect pollinators, especially flies, for fruit set.

The cinnamon butterfly uses this tree as a host plant and can defoliate young specimens, while beetles and leaf miners also feed on the foliage. Aphids, whiteflies, and scale insects present further risks to the plant.

Among diseases, stripe canker, anthracnose, and leaf spot are documented problems affecting this tree.

The tree's inner bark is stripped and dried to yield the spice, which is then used whole or ground. Because ground cinnamon loses its flavor quickly, it is best ground only as needed rather than stored long-term in powdered form.

Culinary: The dried inner bark is ground into a spice used in both sweet and savory cooking, including baking, sauces, pickles, and confectionery, while oils extracted from the bark and foliage serve as flavoring in food and beverages.

Ornamental: Grown as an evergreen specimen for containers, patios, or woodland settings, the tree offers fragrant foliage and bark, along with flowers and fruit that attract butterflies, pollinators, and songbirds.

Industrial: Beyond flavoring, the fragrant oils are also used in the production of soaps and candles.

Medicinal: The plant has a documented history of traditional use for treating a wide variety of medical conditions.

True Cinnamon is native to Sri Lanka, formerly known as Ceylon, a name preserved in one of the species' historical botanical synonyms. Sri Lanka remains the source of the large majority of the world's supply, while the tree has also spread into cultivation in the Seychelles, Madagascar, Tanzania, and parts of Borneo including Sarawak, Sabah, and Kalimantan. Beyond its cultivated range, it has also escaped cultivation on Pacific islands such as Samoa, Fiji, and the Cook Islands.
