Almost all year round, clusters of small, greenish-white flowers hang from the African walnut tree, with each tree bearing both male and female flowers (5). The seeds of the African walnut, contained within the woody, pod-like fruit, are dispersed by the wind, carried by the long wing at the base (3) (6). The length of time for which the seeds can successfully develop once dispersed is short, and the seedlings will only develop when there is a gap in the forest canopy to allow sufficient light to the new plant. The chance of a seed successfully germinating is also hindered by the high probability of it being eaten by a forest-dwelling animal (4) (6). If conditions are favourable and the seedling develops into a mature tree, it is predicted to take an incredible 106 years to reach a trunk diameter of around 2.7 metres (6).
