Banana trees are actually the world's largest herb. The trunk is composed of the main fruiting stem enrobed by leaves. Due to its size, it is often thought of as a tree. While most species grow best in the warmer climates, there are cold-hardy trees.
Grow this plant in a location where it will be sheltered from the wind as it is very susceptible to damaged leaves. Banana plant leaves are huge—depending on the variety, they can be up to 2 feet wide and 9 feet long. Banana plants have a generally irregular shape. Bananas form in late summer in a cluster called a hand. Not all forms are edible; some may be tasty but have large seeds. They start finally ripening the following March. When the fruit is green but plumped up, cut off the stalk and place in a cool, dry space. Stalks can range in sizes from 2.5 feet to 12 feet long. The colors can be yellow, pink, green, or red. The most common type that produces edible fruit is the Cavendish variety.
