Ficus sansibarica
The knobbly fig is a large African fig, typically 10 m tall but up to 40 m as a forest strangler. It has smooth, lumpy grey bark and large figs borne on distinctive wart-like, leafless spurs on the trunk and main branches. It grows in coastal, riverine and evergreen forest and miombo woodland from sea level to about 900 m, often on deep sand. In cultivation it wants full sun, warmth, a free-draining sandy mix and a drier, cooler winter, and it will not survive frost.
Where it grows wild
Wikipedia describes it in coastal, riverine and evergreen forest or woodland and miombo, with a strong preference for deep sandy soils. It is also planted in villages and parks. It begins life as an epiphyte and becomes a strangler as it develops, eventually standing alone as a large tree. The subspecies sansibarica occurs in the east, extending westward along the Zambezi valley, and subspecies macrosperma occurs in West and Central Africa.
Measured records run 3–2,060 m, with a median of 320 m (37 records). Wikipedia gives coastal elevations to about 900 m, so the higher records are unusual.
