Banana plants look like trees because of their trunk-like structures called pseudostems. The structures are tightly packed spiraled layers of leaves.


The actual leaf is made up of sheaths, leaf blades and leaf stalks. The leaf blades are called lamina and the stalks are called stout petioles. Banana plant leaves are very strong. The sturdiness of the leaves allows the pseudostem to support the weight of the plant


A rhizome is an underground stem with parts that branch off above ground called meristems. The bottom of the pseudostem and stalks begin at the meristems. The plant’s roots also begin at the rhizome and extend down into the ground and horizontally.

Fruit and Flowers

Bananas, the edible fruit of the tree, start growing horizontally. As the fruit matures and gets heavier, it starts to hang vertically. Banana plant flowers form in clusters. They are actually green bananas that open up at the top into a flower with purple-red petals.
