High Quality Content by WIKIPEDIA articles! The Dwarf Cavendish banana (or simply Cavendish banana) is a banana cultivar originally from Vietnam and China. It became the primary replacement for the Gros Michel banana in the 1950s after crops of the latter were devastated by the Panama disease. The name `Dwarf Cavendish` is in reference to the height of the pseudostem, not the fruit (which are medium sized). It is one of the most commonly planted banana variety from the Cavendish group, and the main source of commercial Cavendish bananas along with Grand Nain.
