How to Identify Edible and Poisonous Parts of the Taro Plant
Welcome, plant explorers! Have you ever seen a giant green leaf shaped like an elephant’s ear? Maybe you know someone who eats “arbi” or “taro root” curry at home. Today, let’s discover the amazing taro plant, a superstar in tropical gardens and kitchens all over the world.
Say Hello to Taro – The Plant with Many Names!
Meet Colocasia esculenta (That’s Taro’s Fancy Name!)
The taro plant’s science name is Colocasia esculenta. It belongs to the Araceae family, which also has elephant ear plants and even some houseplants. Taro first grew wild in Southeast Asia and India, but now it grows in warm, rainy places all over Africa, the Pacific Islands, and even in backyard gardens. If you see lush green plants with huge, heart-shaped leaves standing tall in wet soil, you might just be looking at a patch of taro!
Where Does Taro Grow Best?
- Taro loves warm, humid weather.
- It grows well in both wet, muddy soils (like rice) and drier garden beds.
- People grow it a lot in India, Southeast Asia, Hawaii, and Africa.
What’s Inside a Taro Plant? Let’s Peek!
Root Power – The Secret Corm
The taro root you see in shops is not a true root – it’s a corm, a fat, starchy underground stem storing food for the plant. This is the yummy part we cook and eat! Little fibrous roots grow from the corm to keep the plant steady.
Giant Green Leaves
Taro leaves are giant and shaped like arrows or hearts. Each has a long, strong stalk called a petiole. The leaves stand proud and shiny above the ground, catching plenty of sunlight. Their veins go mostly in straight lines, which is common in monocot plants.
What About Flowers?
- Taro can make flowers: a creamy spike (spadix) inside a green cover (spathe).
- Most homegrown taro doesn’t flower much – it’s all about those leaves and corm!
How Does Taro Grow? All Its Tricks
Water-Loving and Sun-Friendly
Taro is a water-loving plant, perfect for rainy places. It is super at making food by photosynthesis — those big leaves catch sunlight and turn it into sweet energy stored in the corm.
How Does It Make More Taro?
- Most taro plants grow baby taro plants (offsets or “suckers”) right beside them.
- Farmers cut these off and plant them to get new taro plants! (That’s called vegetative propagation.)
Why Can Raw Taro Make You Itchy?
- Raw taro has sharp crystals (calcium oxalate) in its corm and leaves.
- Eating or touching them can make your mouth or skin itch.
- Cooking destroys these tiny crystals, making taro safe and tasty.
Taro on Your Plate and More!
Edible Uses That Make Taro Special
- The corm is boiled, fried, or mashed – great for curries and chips.
- Leaves (after boiling) become a healthy green veggie, rich in iron and vitamins.
- Taro makes traditional foods like “poi” in Hawaii and “arbi sabzi” in India.
Other Cool Uses of the Plant
- Some people use roasted taro as herbal medicine for tummy troubles.
- Big leaves may be used as natural plates!
- Ornamental varieties decorate gardens with mega-leaves.
Warning! Not Every Taro Relative Is Edible
Many “elephant ear” plants look similar but are not yummy like taro – some can even be poisonous. Always make sure you have the right plant before cooking!

Similar But Different: Table Time!
| Trait | Taro (Colocasia esculenta) | Elephant Ear (Other Araceae) |
|---|---|---|
| Can we eat it? | Yes, corm & young leaves (cooked) | Most are just for decoration, some are poisonous |
| Leaf shape | Heart/arrow-shaped, large & smooth | Heart-shaped, often very big and fancy |
| Grown for | Food and garden beauty | Mostly garden beauty only |
Taro Quick Facts Table
| Feature | What It Means | Fun to Know |
|---|---|---|
| Common Name | Taro | Also called Arbi, Dasheen, Eddoe |
| Scientific Name | Colocasia esculenta | Belongs to the Araceae family |
| Plant Parts Used | Corm (stem), young leaves | Must be cooked before eating |
| Where it grows | Tropical, wet places | India, Southeast Asia, Africa |
| Special Note | Uncooked parts are toxic! | Cooking makes it safe and delicious |
Why Can’t You Eat Raw Taro? Let Vedantu Explain!
That tickly feeling from raw taro is because of tiny needle-shaped crystals hiding inside. But don’t worry, once they’ve had a good boil, they wave goodbye! Boiled taro turns creamy and super yummy for curries and snacks. Vedantu’s science lessons cover how cooking changes food safely.
Fun Example Q&A Time
Q: Is taro a “root” like carrot?
A: Not exactly! A carrot is a true root, but taro’s “root” is actually an underground stem called a corm. Both taste good but grow in different ways!
Q: Can you keep taro as an indoor plant?
A: Yes, if you give it a big, moist pot and enough sunshine. Some people keep taro relatives as houseplants for their giant leaves.
Let’s Practice and Remember!
- Question 1: Name two parts of taro you can eat after cooking.
- Question 2: Why do we need to cook taro before eating?
- Question 3: How can you tell taro and “elephant ear” plants apart?
- Question 4: Which plant part is the “corm” – root or stem?
(Answers: Corm and young leaves; because raw parts are toxic; taro is grown for food, others mostly for decoration; “corm” is a stem!)
Tricky Mix-Ups: Taro Isn’t Always What It Seems!
Many students mix up taro, elephant ear, and even yams. But only taro’s corm and leaves (after cooking) are good for your tummy. Remember: not all big-leafed plants are safe! Stuck remembering? Try this: “Taro for table, elephant ears for garden!”
