Spathodea campanulata is medium sized, reaching a height of 10-35 m, deciduous, with a round, heavy crown of dense, dark foliage, sometimes somewhat flattened; young bark pale, grey-brown and smooth but turns grey-black, scaly and cracked vertically and horizontally with age.

The opposite imparipinnate leaves are exstipulate. Each leaf consists of 5-7 pairs of opposite leaflets and a terminal one. The leaflets are oblong-elliptic, about 1 cm long and 0.5 cm broad, entire, broadly acuminate, unequal at the base, dark green on top and light green on the underside; there are glandular swellings at the base of the lamina (usually a pair); the midrib and nerves are yellow, raised and very slightly pubescent; the venation is reticulate; the short, thick petiole is about 0.7 cm long; there are conspicuous lenticels on the rachis; rachis base is swollen.

Flowers large, red, hermaphrodite, orange inside; calyx green, about 1 cm long and split on the posterior side, ribbed and tomentellous; petals 5, each about 1.5 cm long; stamens 4 with orange filaments; style extruding with a 2-lipped stigma; flower buds curved and contain a red sap. A yellow-flowered variety has been reported.

Fruit upstanding, dark brown, cigar-shaped, woody pod, 15-25 cm long and split on the ground into 2 boat-shaped valves, releasing many flat-winged seeds; 1-4 pods usually develop from 1 flower cluster; seeds thin, flat and surrounded by a filmy wing.

The generic name comes from the Greek word ‘spathe’ (blade), from the shape of the corolla. The specific name means pertaining to a Campanula, a name coined in 1542 by Fuchs for the type of corolla with a broad rounded base and a gradually expanded tube corresponding to the sound bow of a church bell.

Ecology

S. campanulata grows naturally in Africa in secondary forests in the high forest zone and in deciduous, transition, and savannah forests. It colonizes even heavily eroded sites, though form and growth rate suffer considerably on difficult sites.

Native range
Angola, Ethiopia, Ghana, Kenya, Sudan, Tanzania, Uganda, Zambia

Tree management

S. campanulata will coppice up to at least pole size.

Seed storage behaviour is recalcitrant; seed should be sown fresh. From its seed size, the species might be able to show orthodox storage behaviour. There are about 125 000 seeds/kg.

S. campanulata grows naturally in Africa in secondary forests in the high forest zone and in deciduous, transition, and savannah forests. It colonizes even heavily eroded sites, though form and growth rate suffer considerably on difficult sites.

Natural reproduction takes place on bare ground, in grass, and under weeds and brush. Seeds may be collected by harvesting the pods after they turn brown and allowing them to air-dry until they split open. The germinating seeds are fragile and should be covered by a thin film of peat or sand and should not be exposed to hard rain. Vegetative reproduction is easily carried out with cuttings or root suckers.

Poison:  The hard central portion of the fruit is used to kill animals.

S. campanulata helps rehabilitate disturbed lands through its quick invasion and rapid growth.

  The seeds are edible and used in many parts of Africa.

Timber:  In its original habitat, the soft, light brownish-white wood is used for carving and making drums.

Shade or shelter:  Recommended as a shade tree for parks and yards; it has been used for coffee shade.

Medicine:  The bark has laxative and antiseptic properties, and the seeds, flowers and roots are used as medicine. The bark is chewed and sprayed over swollen cheeks. The bark may also be boiled in water used for bathing newly born babies to heal body rashes.

Ornamental:  S. campanulata has been planted as an ornamental throughout the tropics. The flowers bloom with great profusion, and the trees can be seen from great distances. It is not browsed by domestic animals and although a popular  decorative tree for avenues it has shallow roots and a tendency for branches to break off in a storm.

The species, either planted or growing naturally, is frequently used for living fence posts.
