Japanese Horseradish. The root is prized as a condiment in Japan. Very hot and akin to a hot mustard flavour, and gaining a lot of interest in the west. The plant takes two years to reach maturity. Best in moist, shady conditions and acid soil. The plant will produce offsets, so after harvesting the big root, replant the offsets. It is summer dormant, so don’t worry when it disappears in midsummer. Hardy. Priced for: a 2 year old plant in a 3 litre pot
