Ficus lutea aka Dahomey Rubbertree

Ficus lutea is an African tree in the mulberry family, Moraceae. Its names include Dahomey rubber tree, Lagos rubber tree, and Zulu fig. Its range runs from Senegal east to Ethiopia. It extends south to Angola, South Africa, and Madagascar. It grows in wooded savannah and forests at several elevations. It also occurs near streams, swamps, and cleared land.

The tree reaches about 49–66 feet [15–20 metres] tall. Large branches spread out from a short trunk. The trunk often has buttresses and can reach 10 feet [3 metres] around. The tree sheds its leaves for a short time. It often starts as an epiphyte on another tree's branch. Aerial roots grow down and take hold in the soil. These roots thicken and can surround the host's trunk. The fig's leaves also shade the host's crown. Together, these effects can kill the host tree.

Small figs grow along the stems and can form heavy crops. They reach about 0.06 feet [0.017 metres] across. Their colours range from yellow through orange to brownish tones. People eat the fruit raw. Wasps pollinate the tree, with breeding tied to the figs. Useful Tropical Plants lists no known hazards. This does not establish safety for pets or every plant part.

This fig suits warm tropical sites with ample rain. It grows best at daytime temperatures of 22–30°C. The reported tolerance range is 15–35°C. Full sun suits it best, though it also grows in light shade. It accepts varied fertile soils where water drains well. It prefers acid soil, with a reported pH range of 4–5.5. It also withstands strong winds and salt spray. Growers plant it for shade in villages and as an ornamental tree.

The bark provides fibre for twine and material for bark cloth. It also yields a red-ochre dye for textiles. Latex has uses in medicine, canoe sealing, and rubber making. The wood supplies material for bowls. Its ashes provide potash for soap making. Traditional remedies use boiled bark preparations for several ailments. These reported uses do not prove that treatments work or are safe. Growers can raise the tree from seed, tip cuttings, or air layering. Seeds germinate best near 20°C and may take 10–30 days.
