A plant that is uninspiring to look at resembling a weed (with leaves like dock weed), and naturally invasive by nature, horseradish is best grown in a large container or wild part of a garden when it can rampage without worry. The plant is grown for its strong, fiery roots that are the main ingredient in horseradish sauce. Like parsnips, that taste of the roots is said to improve with a hard frost, and the roots are usually harvested in autumn once the foliage has died back.
Horseradish is usually grown from roots that can be bought from garden retailers in the spring.
