Baphia nitida aka Camwood

Baphia nitida is challenging to grow outside its native tropical environment. It requires specific conditions including full sun (cannot tolerate shade), consistently warm temperatures between 24-30°C, high humidity, and substantial annual rainfall of 1500-2400mm. The tree is only hardy to USDA zones 10-12 and UK zone 10, making it unsuitable for temperate climates without heated greenhouse conditions.

Baphia nitida prefers consistently moist soil and originates from rainforest and wet coastal regions with annual rainfall of 1500-2400mm. Water regularly to maintain soil moisture, but ensure good drainage as the species does not tolerate waterlogged conditions. During active growth, the soil should never dry out completely. Reduce watering slightly during cooler periods but never allow the rootball to become completely dry.

Baphia nitida is adaptable to various soil types including light sandy, medium loamy, and heavy clay soils. It prefers well-drained, fertile, medium-textured soil but tolerates a wide pH range from very acidic (pH 4.5) to mildly alkaline (pH 7), with an optimal pH of 5-5.5. As a nitrogen-fixing legume, it improves soil fertility through symbiotic bacteria in its root nodules.

Native to tropical rainforests of West Africa, Baphia nitida thrives in high humidity environments. The species naturally occurs in regions with 1500-2400mm annual rainfall and wetter coastal areas. In cultivation outside the tropics, maintaining elevated humidity is important for healthy growth, particularly when grown in enclosed environments like greenhouses.

Baphia nitida propagates readily from both seeds and cuttings. For cutting propagation, use material from younger parts of the plant for best results. Seeds can be sown in moist, well-draining growing medium in warm conditions. As a legume, fresh seeds typically germinate well without scarification, though older seeds may benefit from soaking before sowing.

Baphia nitida is a many-stemmed shrub or small tree that typically reaches 2.5-10 metres in height with a spread of up to 10 metres. It develops a dense, bushy crown and can grow up to 45cm in trunk diameter. In its natural rainforest habitat, it often grows as an understory tree. Growth rate is moderate under optimal tropical conditions with adequate moisture and full sun.

Yes, Baphia nitida produces attractive fragrant white pea-like flowers with distinctive yellow centres. The papilionaceous (butterfly-shaped) blooms appear in small axillary clusters of 1-5 flowers on slender pedicels. Each flower features a suborbicular standard petal 1-2 cm in diameter. After pollination, the tree develops compressed seed pods 8-16.5cm long containing 1-4 brown seeds.

Baphia nitida is pollinated by insects (entomophilous pollination). The fragrant white and yellow flowers attract various pollinators including bees and butterflies. The papilionaceous flower structure, typical of the legume family, is particularly well-suited to bee pollination, where visiting insects must push into the flower to access nectar, facilitating pollen transfer in the process.

Baphia nitida can only grow outdoors in tropical and subtropical regions corresponding to USDA hardiness zones 10-12 and UK zone 10. It requires frost-free conditions with temperatures ideally between 24-30°C and can tolerate a range of 16-32°C. The species naturally grows from sea level to 600 metres elevation in wet coastal regions, rainforests, and secondary forests across West Africa.

Baphia nitida thrives in tropical temperatures with an optimal range of 24-30°C (75-86°F). It can tolerate temperatures between 16-32°C (61-90°F) but is not frost hardy and should not be exposed to temperatures below 10°C. This tropical species requires consistently warm conditions year-round and is only suitable for outdoor cultivation in frost-free climates.

The seeds of Baphia nitida are edible and are consumed by the Igbo people in Nigeria. The twigs are also used as traditional chewing sticks for dental hygiene. PFAF rates the plant's edibility as 2 out of 5, indicating limited food value. Additionally, the leaves serve as nutritious fodder for livestock with high protein content, particularly valued in Ghana for cattle and sheep.

Baphia nitida has extensive traditional medicinal uses in West African medicine. Research has confirmed the presence of active compounds including saponins, flavonoid glycosides, tannins, and pterocarpin. Traditional applications include leaf ointments for anti-inflammatory and analgesic purposes, powdered heartwood mixed with shea butter for sprains and rheumatic pain, bark decoctions for epilepsy and cardiac issues, and various preparations for gastrointestinal problems, skin conditions, and female fertility.

Baphia nitida was historically one of the world's most important natural dye sources. The heartwood contains up to 23% dye compounds (santalins A and B, santarubins) producing a rich red colour 3-4 times more potent than other redwoods. Exported to Europe from the 17th century for dyeing wool, cotton, and silk. The extremely hard, durable wood is used for house posts, tool handles, walking sticks, and furniture. The tree also serves as an ornamental shade tree and hedge plant.

Baphia nitida can be pruned to maintain shape and control size, particularly when grown as a hedge. Pruning is best done during the dormant season or after flowering has completed. As a multi-stemmed shrub or small tree, it responds well to formative pruning to develop a desired structure. When grown as a hedge, regular trimming encourages dense, bushy growth.

Yes, Baphia nitida produces fragrant flowers. The white pea-like blooms with yellow centres emit a noticeable scent that helps attract insect pollinators including bees and butterflies. The pleasant fragrance is typical of many legume flowers and adds to the ornamental appeal of this species when in bloom.
