A whole book about fig trees? That’s right! If you’re a voracious nonfiction reader like me, you’ll find freelance journalist Mike Shanahan’s history of fig trees unexpectedly fascinating. It opens with him atop a series of ladders in a national park in Borneo, reaching past a venomous snake to pick some figs. He did many such exciting things in his research towards a PhD in rainforest ecology, but that 1998 encounter was significantly more intrepid than his earliest experience with the genus: he remembers a potted weeping fig in the hallway of his childhood home.

From that little tree to the largest banyans, Ficus encompasses 750+ species and has had a major place in human culture for millennia. Fig trees turn up in Greek origin myths and are sacred to Hindus. Romulus and Remus were rescued from drowning in the Tiber by fig tree roots. The tree the Buddha sat under to meditate? A fig. The fruit Adam and Eve ate in the Garden of Eden? More likely a fig than an apple given the Middle Eastern climate and the fact that they then sew fig leaves together to cover their nakedness. (The confusion may have come about because in Latin malum means either “apple” or “evil”.)

Figs offer some biological surprises. For one thing, the plants have no apparent flowers. That’s because the flowers are internal: a fig is not technically a fruit but a hollow ball lined with tiny flowers that must be pollinated by two-millimeter-long fig-wasps. Strangler figs colonize a host tree, starting as a seed in the canopy and enveloping it in long tangled roots. Many tropical birds and mammals rely on figs, including monkeys and hornbills. Figs were, Shanahan writes, the “original superfood” for our primate ancestors.

The habitats where fig trees thrive face severe challenges, including drought, forest fires and poaching. However, history offers encouraging examples of how fig species can be key to tropical forest restoration. After a volcano erupted on Papua New Guinea in 1660, for example, the razed land was fairly quickly recolonized by Ficus species from seeds dropped by birds and bats – a prerequisite for wildlife returning. Similarly, fig trees were all that remained of the forest on Krakatoa after its famous volcanic eruption in 1883.

Building on this precedent, the Forest Restoration Research Unit, based in Thailand, now uses fig species to kickstart the restitution of tropical landscapes; one in every five of their plantings is a fig. Likewise, figs can be used to restore post-mining landscapes and lock up carbon. Researchers are looking into using drones to collect and deposit the seeds.

I’d never realized how often figs show up in the historical record, or how dependent on them we and other creatures have been. “Look after fig trees and they will look after you. It’s a lesson we have all but forgotten, but one we could learn again,” Shanahan concludes. Have a look at the bibliography and you’ll see just how much information is synthesized into this short, engaging book. It’s another gorgeous design from Unbound, too: the colorful cover was what first attracted me, and the author’s black-and-white pointillist illustrations adorn the text.

Nowadays I tend to think of figs as an exotic, luxury food. Every year we add some dried figs to our Christmas cake, creating caramel bursts of crunchy seeds. When my husband and I lived in Reading, we briefly had a LandShare arrangement to look after an established garden. Hidden behind a suburban fence, it was a secret paradise overflowing with fruit: plum, greengage and apple trees plus a fruit cage containing berries, currants, and – in one corner – a small fig. I remember one glorious late summer when we were inundated with more ripe figs than I’d ever seen before. We would heat them in the oven and serve them split open and oozing with goat’s cheese and runny honey. Our very own taste of Eden.
