Apicultural value A savanna honey bee plant with multiple uses Bombax costatum produces an abundant supply of nectar and is recommended for honey production.Family BombacaceaeCommon names English Kapok tree red-flowered silk cotton tree French   Kapokier Hausa  Gurjiya Fulfulde  Jooyehi Joohi Mandinka  Bunkungo Wolof   KattupaDistribution West Africa:  widespread in savanna zones from Senegal to Central African RepublicFlowering period November to FebruaryDescription Bombax costatum is a deciduous tree that can grow up to 25 m high. However in the Sahel it rarely reaches over 6 m. The crown structure of young trees is storeyed becoming irregular and sturdy in older trees. Bark thick grey brown and corky with typical conical stout sharp-pointed spines on the stem and branches. Leaves are compound digitate with 5-7 leaflets 8-15 cm long on long petioles. Leaflets are partly ovate partly acuminate at both ends with 8-10 pairs of lateral nerves. Flowers are 5-6 cm long and solitary deep red orange or yellow tulip-shaped on long glabrous peduncles and are calyx cup-shaped. Fruit is a dark brown ellipsoidal capsule composed of five valves dehiscent 8-16 cm long and 3-6 cm wide of variable shapes. The valves are furrowed for about one third the distance from the top to the middle.  The fruit contains a white floss - kapok - and several small seeds.   Habitat Bombax costatum grows in savannas and dry woodlands. It does well on cropland near settlements and on stony soils. Cultural notes Direct seeding is a preferred propagation mode however wildlings may also be used. The seedlings are difficult to plant in spite of their vigorous rooting ability. Natural regeneration is easy and abundant when sufficiently protected against fire and livestock.Association with bees Bombax costatum flowers during the major dearth period.  This underscores its importance in maintaining honey bee colonies since beekeepers do not need to feed their colonies at all. The end of its flowering period overlaps with the beginning of the flowering of other important bee forage plants including Parkia biglobosa and Vitellaria paradoxa with which it is often associated.  Details on the seasons and nectar flow in this region may be found in Dukku 2003.Honey bees forage for nectar on this tree throughout the day. Other foragers include ants birds flies stingless bees Trigona spp and wasps. Honey bees have been observed foraging on fallen flowers.Other uses Bombax costatum is used as a shade and ornamental tree on farms and compounds. The kapok from the fruit is used in filling mattresses and pillows. The timber is used in making canoes stools and serving bowls. The calyx is used in making soups and the leaves are a good fodder for livestock. The kapok tree is a source of herbal medicine in many communities.References ANON 2010 AgroForestryTree Database World Agroforestry Centre website DUKKU U.H. 2003 Acacia ataxacantha:  a nectar plant for honey bees between two dearth periods in the Sudan Savanna of Northern Nigeria.  Bee World 84 1: 32-34.
