Have you ever eaten a taro vegetable? Taro is a common name for corms and tubers. This is native to South India and Southeast Asia, including my country Philippines. I grow up eating this type of vegetable. You can cook both the roots, the stem , and the leaves. We used to cook this with coconut milk and it's delicious!
A friend of mine gave me some roots to plant so I am trying to grow it in pots. I tried putting it in my garden but the moles keep eating the roots so I dug it out and transferred it to the pots. I hope that it will grow thick so I can dry the leaves and preserve it so I can cook them when I I am craving for it.
Some calls this an elephant ears, that's what I I heard when I first seen it in the store here being sold as an ornamental plant. I was like, "Oh my, that is vegetable for us and over here, it;s ornamental". I love it's starchy corm. I believe it is a staple food in Africa, South Indian cultures, and some parts of Asia.
