The banana on your counter is technically a berry that grows on a giant herb, is slightly radioactive, and is a sterile clone that cannot reproduce on its own. This deep dive traces how a seedless mutant from New Guinea became the most exported fruit on the planet.

We explore the pseudostem, triploid genetics and propagation by suckers, the spread of bananas by Austronesian sailors and Islamic traders, and the rise of vertically integrated fruit companies behind the term banana republic. Then we look at ethylene ripening rooms, the Cavendish monoculture, the Panama disease TR4 threat, and the slow work of breeding and preserving new varieties.

• Why banana plants have no wood and can grow leaves up to five feet in a day
• How stratigraphic mixing may explain disputed early banana evidence in Africa
• How ethylene gas and enzymes turn green bananas uniformly yellow
• Why breeding a TR4-resistant replacement requires colchicine and chromosome doubling
• Banana peels as water filters, abaca fiber, leaf wrappers and the $120,000 duct-taped banana
