Hardy perennial plant (Armoracia lapathifolia) of the mustard family, native to Mediterranean lands and grown throughout the temperate zones. Its hotly pungent, fleshy root is used as a condiment and is traditionally considered medicinal. In many cool, moist areas it has become a troublesome weed. The plant bears small white flowers, small oblong pods, and large, coarse, glossy-green basal leaves arising on long stems from the crown atop the large white root.
