Family Brassicaceae

Horseradish is a perennial vegetable and aromatic plant known for its white root with a powerful, pungent, and very spicy flavor. Widely used as a condiment, it brings a lively and biting flavor to sauces, marinades, meats, fish, sandwiches, potatoes, beets, vinaigrettes, and traditional recipes. Its large, green foliage also adds a beautiful presence to vegetable gardens, useful plant gardens, and edible landscapes where a robust and durable plant is desired.

Easy to grow, horseradish prefers a sunny to slightly semi-shaded location, in deep, rich, fresh, and well-drained soil to allow its root to develop properly. It appreciates regular watering during the growing season, especially in hot weather, to obtain fleshier and better-quality roots. As it can become vigorous and regrow from root fragments, it is best to plant it in a well-defined area or a large container to better control its expansion.

Both productive, hardy, and very useful in the kitchen, horseradish is ideal for gardeners looking for a distinctive and flavorful edible plant. Its root is usually harvested when the plant is well established, then grated fresh to release all its aromatic intensity. It is an excellent plant to enrich a gourmet vegetable garden, a herb garden, or a collection of traditional plants with a strong, distinctive, and sought-after flavor.
