Indian turnip is a root vegetable that is known for its striking appearance. It is also known by several other names such as Jack-in-the-pulpit, bog onion, wild turnip, and arum lily. The plant is native to North America but is found in many other parts of the world as well. The name 'Jack-in-the-pulpit' comes from the shape of the flower which resembles a preacher in a pulpit. The plant is called 'wild turnip' due to its tuberous root which is edible but must be cooked thoroughly to remove the sharp taste. Arum lily is another popular name for Indian turnip because of its striking resemblance to the lily flower.
