COMMON NAME: Tamanu, Beach Calophyllum
Plant Profile
Calophyllum inophyllum, commonly known as Tamanu, is a species with a long record in gardens. When it flowers, local bees and other insects make good use of it. Together these qualities explain its long-standing appeal to gardeners.
Science & Biotechnology
The species features in the wider study of the Calophyllum group, and its traits make it a useful subject for work on germination biology, cultivation and ornamental selection. Separately, its high oil content has also drawn agricultural research interest as a potential tropical biodiesel feedstock, positioning species at intersection of traditional Pacific plant use and contemporary renewable energy and cosmetic science research. Nothing exotic is required: standard seed-sowing practice, done carefully, is enough.
Uses & Benefits
Gardeners value Tamanu for its ornamental character, and the plant also fits naturally into herb, vegetable and cutting gardens. Its salt tolerance and substantial size also make it a valuable coastal windbreak and shade tree across its native tropical range. Beyond the establishment year, its needs are simple and few.
Tamanu tree seed oil is a prized Pacific folk remedy for skin repair, and the genus drew scientific attention when calanolide compounds from related species entered anti-HIV research.
Growing from Seed
Seed is the natural starting point for Tamanu, and the process is uncomplicated. Fresh seed is best; sow it into a loose, well-drained tropical mix and keep it warm and consistently moist. Bright light suits young tree well, and given its coastal origin, it tolerates salt spray and sandy soil considerably better than most trees once established. Level a tray of loose seed compost, sow evenly, cover to about the seed’s own depth, and keep it moist in full light. Prick the seedlings out once they are large enough to handle, grow them on in bright light, and plant out when conditions allow.
Our Take
Tamanu, Beach Calophyllum has real presence in the garden without demanding much in return. Part of this plant’s appeal is the long practical history summarized above. Plant it in sun with drainage to its liking and the rest is easy.
