What Are Bananas?

A banana is a fruit from any of several species in the plant genus Musa, which is native to the tropical regions in Southeast Asia. The plants they grow on are often called "banana trees," but they are actually giant herbs that can grow to around 3 m (9.8 ft) tall. The fruits themselves have a tough outer peel and a soft, fleshy interior, with tiny black seeds dotting the middle.

Bananas are often eaten by humans and are an excellent source of vitamins and minerals, especially potassium, which helps keep our muscles and nerves working properly. They also have fiber, which is important for a healthy digestive system. Bananas can be eaten on their own or used in a variety of recipes, from smoothies to baked goods.

Did you know?

  • Banana trees aren't actually trees.

    Instead, they're what scientists call an "herbaceous plant." Herbaceous plants are different from trees because they don't have woody stems or branches that grow thicker over time. Instead, they have soft, fleshy stems that grow quickly and are replaced each year.

    Banana plants grow from underground bulbs called corms, and their stems are made up of tightly packed leaves that wrap around each other. As the stem grows taller, it produces new leaves at the top, which is where the bananas themselves grow. Once a banana plant has produced bananas, it will stop growing and eventually die back, but new plants can sprout up from the corms to continue the cycle.

  • We're pretty used to seeing our favorite curved fruits with green, yellow, or even spotted-brown skin, but did you know that some bananas come with totally different colored peels?

    Most of us know that as bananas ripen, their peels can turn from green to yellow, and eventually to brown or even black. But it turns out that's not all! Some bananas have naturally different colored peels. For example, the Red banana has a reddish-purple peel, the Blue Java banana has a bluish-grey peel when not quite ripe, and the Velvet Pink banana even has a pink peel!

  • Bananas are technically classified as berries.

    When we think of berries, we often picture small, round fruits like strawberries, raspberries, and blueberries. But, as it turns out, scientists classify berries as any kind of fruit that grows from a single flower and has seeds inside.

    Because of this, bananas are berries too, even though they look very different! Bananas grow from a single, pretty unusual-looking banana flower and have tiny black seeds inside—they're so small you might not even think of them as seeds.

  • As sad as this makes us, monkeys in the wild don't actually eat bananas.

    According to Berkeley University primate scientist Katherine Milton, "Wild monkeys never encounter bananas at all ever unless they are around human habitation where bananas are or have been planted." In nature, monkeys' diets almost exclusively consist of small fruits, leaves, nuts, and insects. In fact, some animal nutritionists suggest not feeding bananas to monkeys, as bananas contain larger amounts of sugar and calories than monkeys are typically accustomed to consuming.

  • The world record for fastest marathon run while wearing a fruit costume was accomplished while wearing a banana suit.

    On April 25, 2016, 30-year-old Andrew Lawrence shattered the previous 2 hour 58 minute record run by Patrick Wightman in the 2011 Barcelona Marathon. Dressed as a bright yellow banana, Lawrence completed the London Marathon in 2 hours, 48 minutes, and 41 seconds.

  • If you went to a grocery store in the 1950s, you probably couldn't find the bananas you're eating today.

    While it's estimated that there are over 1,000 varieties of banana grown today, by far the most popular is the Cavendish banana, making up approximately 47% of worldwide production. Up until the first half of the 20th century, however, the most common variety was the Gros Michel, or "Big Mike" banana. Gros Michel bananas had thick, study peels, and grew in large, dense bunches that made them easy to ship. In the 1950s, a fungus known as Panama disease all but wiped out production, forcing cultivators to switch to varieties resistant to the disease, including the Cavendish.

  • Closed in 2022, California's International Banana Museum once housed the world’s largest collection devoted to a single fruit.

    Opened in 1976 and located in Hesperia, California, the International Banana Club Museum once contained more than 17,000 banana items. Most artifacts were been donated by members of the official Banana Club, of which there are over 35,000 in 27 different countries.

    As of 2022, the museum is unfortunately permanently closed due to complications from the COVID-19 pandemic.
