Sycomore figs 2 are found throughout tropical Africa. In Southern Kenya they thrive along river banks.
This is the story of one of those trees.
Our African queen is a mature sycomore fig 1. She started life as a seed one hundred years ago.
She provides for many animals. To some, she is a hunting ground; to others, she is home. She feeds a greater variety than any tree in Africa. All rely on her tiny fig wasp 3 partner that only a few even notice.
Every few months, the queen produces up to a ton of fruit. To reproduce, she must transfer pollen 4 to make seeds and then disperse 5 them inside the figs. The last crop fell only days ago. But up above, she is starting again.
Over the next two weeks, the tiny buds swell 6 to become young figs.
Hidden inside each are the queen’s tiny flowers. At this stage a fig is not a fruit, but a secret garden whose delicate perfume attracts a flock of fig wasps 7. Their arrival will trigger a sequence of events that will resonate out through the bush.
