About Horseradish
Armoracia rusticana, commonly known as horseradish, is a vigorous perennial plant from the Brassicaceae family, valued for its fleshy, pungent root. It develops large, elliptical leaves forming a basal rosette, and in summer produces spikes of small white flowers. It's an ideal plant for vegetable gardens or herb gardens, where its lush foliage can provide a good contrast.
Native range
Eastern Europe and Western Asia
Care tips
It prefers full sun to partial shade and deep, moist, well-drained soils; a substrate rich in organic matter will promote good root development. Regular watering is required to keep the soil consistently moist, especially during dry periods. A common mistake is planting it directly in the garden without containment, as its roots are very invasive and it can become difficult to control; it's best grown in large containers or with underground barriers.
