Banana is a fruit that comes from a herbaceous plant, the banana tree. 
The banana tree is a herbaceous plant that is characterised by three phases during its development cycle: a vegetative phase of 6 to 8 months, a flowering phase of 3 to 4 months, and a fruiting phase of 3 to 4 months.
Rich in potassium, the banana helps regulate blood pressure, protects the body from cardiovascular accidents and may limit the formation of kidney stones. Its richness in fibers facilitates intestinal transit.
