The banana plant is the largest herbaceous flowering plant.[4] Banana plants are often mistaken for trees. Bananas have a false stem (called pseudostem), which is made by the lower part of the leaves. This pseudostem can grow to be two to eight metres tall. Each pseudostem grows from a corm. A pseudostem is able to produce a single bunch of bananas. After fruiting, the pseudostem dies and is replaced. When most bananas are ripe, they turn yellow or, sometimes, red.
