Horseradish presents as a robust, perennial herb with large, coarse, basal leaves measuring up to 2 feet (60 cm) long. These leaves showcase a deep green hue with a glossy surface and are notably crinkled with a distinctive, sinusoidal margin. The plant gives rise to white, four-petaled flowers arranged in terminal clusters atop stiff, erect flowering stems which can reach 5 feet (1.5 meters) in height. The stout, fleshy taproot is pivotal for identifying horseradish, appearing notably larger than the fibrous secondary roots.
