Horseradish is a perennial vegetable or herb that is primarily grown for its pungent roots. This is the same horseradish that most people buy in a jar and use to spice up a variety of dishes, from roast beef to cocktail sauce, and to complete a Passover Seder plate. Horseradish leaves can also be eaten when they are young and tender, but they should not be eaten by animals because they are mildly toxic to them.
Horseradish (Armoracia rusticana) is a clump-forming perennial plant in the Brassicaceae family. It is grown from root divisions and can be aggressive. If you worry about horseradish spreading too far, you can plant it within barriers—or you can grow it in a container, where you have the option of growing it as an annual plant with a single large root.
Horseradish is normally planted in spring. It will quickly grow and be ready to harvest by fall.
