Raphanus caudatus, commonly known as the rat-tail radish, is a species of edible plant in the Brassicaceae family, which also includes mustard, cabbage, and radish. Unlike the common radish, which is grown for its root, Raphanus caudatus is cultivated for its edible seed pods. The plant is notable for its long, slender, tail-like pods, which can grow up to 20-30 cm in length. Originating from Southeast Asia, it has been widely cultivated across the world for its unique flavor and texture.

These pods contain edible seeds and are harvested before they mature fully.
