Every picture book draws a banana hanging from a woody trunk like an apple tree. Plantations look the part from a distance. Up close there is no true wood. A banana plant is a giant perennial herb whose “trunk” is a pseudostem of tightly wrapped leaf bases, and botanists even class the fruit as a berry. Tall enough to fool anyone, woody enough to count as a tree—it is not.

Bananas grow on trees
What we know now
Bananas do not grow on trees. Michigan State University Extension notes they are fruit of the world’s largest herb: the upright “trunk” is a pseudostem made of packed leaf bases, not woody tissue. The fruit is botanically classified as a berry (seeds develop inside the flesh). Commercial Cavendish bananas are typically propagated by cuttings and are parthenocarpic, producing fruit without pollination.
Yes — and not as a joke question on a quiz. This science claim showed up in textbooks, worksheets, and classroom posters through the 2020s, which is why so many people still remember it as settled fact long after the science moved on.
Is "Bananas grow on trees" true?
No. Bananas do not grow on trees. Michigan State University Extension notes they are fruit of the world’s largest herb: the upright “trunk” is a pseudostem made of packed leaf bases, not woody tissue. The fruit is botanically classified as a berry (seeds develop inside the flesh). Commercial Cavendish bananas are typically propagated by cuttings and are parthenocarpic, producing fruit without pollination.

When was this understanding updated?
The evidence had largely shifted by around 2022. Schools don't flip overnight, though — plenty of classrooms kept teaching the older version for years after researchers had already moved on.
