Cinnamomum aromaticum Seeds | Cassia Cinnamon
LATIN NAME: Cinnamomum aromaticum
COMMON NAME: Cassia Cinnamon
Plant Profile
Cassia Cinnamon (Cinnamomum aromaticum) is an evergreen tree of the laurel family (Lauraceae), native to southern China and mainland Southeast Asia. It reaches 10-15 m, with glossy, leathery, three-veined leaves and clusters of small white flowers followed by dark berries. The thick, rough bark is the cassia of commerce — the cinnamon of the American market — and unopened flower buds are also dried as a spice.
Science & Biotechnology
Cassia is the cinnamon of commerce and of most cinnamon research. Its bark oil is dominated by cinnamaldehyde, responsible for the antimicrobial and much-studied metabolic activity; trials of cassia in type 2 diabetes have produced mixed results on blood glucose, with meta-analyses finding at most modest benefit. The important safety distinction from Ceylon cinnamon (C. verum) is coumarin: cassia carries far higher levels, and regular high intake can exceed the tolerable daily coumarin intake, a hepatotoxicity concern that European food regulators take seriously. Culinary amounts remain a pleasure without a problem.
Within the Cinnamomum group, Cinnamomum aromaticum is of continuing interest to researchers working on plant diversity, seed biology and the selection of improved garden forms. This coumarin difference has become a frequently discussed subject in comparative spice safety research distinguishing cassia from true Ceylon cinnamon. With present-day seed handling, raising this species well within the reach of any careful grower.
Uses & Benefits
Gardeners value Cassia Cinnamon for its ornamental character, and the plant also fits naturally into herb, vegetable and cutting gardens. Understanding which cinnamon you actually have, cassia or true Ceylon, is useful for anyone monitoring coumarin intake specifically. Once settled, it thrives on neglect more than on fussing.
Cinnamon is a spice and a medicine chest: its bark oil and polyphenols are studied for post-meal blood-sugar support, and cassia bark, Rou Gui, is a major warming herb of Chinese medicine. The leaf oil supplies eugenol for dentistry and flavoring.
Growing from Seed
Raising Cassia Cinnamon from seed is straightforward. Fresh seed is best; sow it into a loose, well-drained tropical mix and keep it warm and consistently moist. Bright, filtered light suits young tree well, and several years of growth are needed before bark suitable for spice harvest develops. Sow thinly on the surface of a loose, well-drained seed compost, cover lightly, water in gently and keep the tray in a sunny spot with even moisture. Once the seedlings have made true leaves, pot them on individually and plant out when they are sturdy and conditions are right.
Our Take
It is a solid representative of the Cinnamomum group, true to type from seed. Sun, free drainage and a patient first year are all it really requires.
