Some bananas grow only a few feet tall, while others surpass 30 feet. And size isn't the only thing to consider. There are ornamental bananas and edible bananas, sweet bananas and starchy bananas, and even bananas that can be grown in containers.
Ornamental bananas. Not all bananas are grown for the table, and while all of them are attractive enough to be grown as ornamentals, these species are grown exclusively for their looks. Pink flowering banana (Musa ornata, zones 8b to 11), shown, produces stunning lavender-pink flowers on upright stalks, held aloft right at eye level. Chinese yellow banana (Musella lasiocarpa, zones 7b to 11) is a close relative of the banana and is also grown primarily for its impressive bloom. The Japanese fiber banana (Musa basjoo, zones 6 to 11) is the cold-hardiest banana and can be grown in temperate zones with protection. Abyssinian banana (Ensete ventricosum, zones 9 to 11) has dramatic upright leaves with prominent ribs.
Plantains. Starchy plantain-type bananas are a suitable replacement for potatoes and other starch crops in the tropics and are excellent served up fried. They have found their way into Latin American, Caribbean, African and Southeast Asian cuisines, but most shoppers in Britain and the United States know them only as "green bananas." They do require cooking before being served.
Some choices for your garden include Ae Ae (Musa X paradisiaca 'Ae Ae', zones 10 to 11), Dwarf Orinoco (Musa x paradisiaca 'Dwarf Orinoco', zones 7b to 11) and Mysore (Musa x paradisiaca 'Mysore', zones 10 to 11).
In containers. Whether you lack the space, live outside the tropics or just need a dramatic focal point in your container arrangements, there are several bananas with the right size for the job. Super Dwarf Cavendish (Musa acuminata 'Super Dwarf Cavendish', zones 9b to 11) is an even shorter version of the dwarf Cavendish, reaching only a few feet tall. Siam Red (Musa acuminata 'Siam Red', zones 10 to 11) has intense orange-red leaves variegated with green. Red Abyssinian banana (Ensete ventricosum 'Maurelli', zones 9a to 11) is a banana relative that also has red leaves, but they are upright and give the plant the appearance of a shuttlecock. They can get quite large but will last a few years in a container.
If you're growing edible types, just remember that you will need to harvest the fruit and thin out the declining stems, which means that the plantings (if any) beneath the bananas should be durable enough to handle occasional foot traffic.
Ornamental bananas are ideal as focal points in a bed of perennials or ground covers, and occasionally as specimens surrounded by open space. Smaller types look superb when massed together like cannas.
Try using pink velvet bananas (Musa velutina, zones 7b to 11) and red bananas (Musa acuminata 'Red Dacca', zones 9 to 10) for their small size and unexpected hues. Nothing says tropical style like a freshly cut "hand" of bananas on the kitchen counter.
Believe it or not, bananas are pretty carefree once they're established. Though they are tolerant of many conditions, they thrive best with lots of ample sunlight, moisture and fertilizer.
Planting. Amend the planting site with plenty of compost or topsoil and keep the banana watered, especially during its first months in the ground. Feed it on a regular schedule according to the fertilizer's label instructions.
When the banana blooms, the flower (rather a collection of flowers) will hang downward and form bananas as it descends. Remove the banana "hands" with a sharp knife or machete as soon as they reach a mature size, leaving the bloom in place to form new fruits. When the bloom is spent, the stem will die. Cut the entire stem to the ground, allowing the other stems to take its place. The stem can be chopped up and spread over the planting site as an effective mulch.
