Wasabi is an herbaceous perennial native to Japan and Korea, belonging to the Brassicaceae family alongside cabbage, horseradish, and mustard. It naturally grows along rivers and streams in mountainous areas and thrives in cool, moist, humid environments similar to fern habitats. The plant's rhizome is edible and provides a pungent spiciness comparable to horseradish, traditionally grated into a fresh green paste used as a popular Japanese condiment. All parts of the plant are edible, with rhizomes requiring up to three years to mature to a harvestable size of approximately 1 inch in diameter.
