Horseradish (*Armoracia rusticana*) is a hardy perennial plant in the mustard family (Brassicaceae) cultivated mainly for its pungent fleshy root, which is used as a condiment. It is native to parts of southeastern Europe and western Asia and is now grown widely in temperate regions, including in home gardens and specialty agriculture across Canada. The plant is known for its aggressive growth and can become invasive in some areas.
Description
Horseradish is a vigorous herbaceous perennial with large leaves, small white flowers, and a thick fleshy root. The root contains pungent sulfur compounds that create its sharp flavour. The leaves are edible but are much less commonly eaten than the root.
Cultivation and distribution
The plant is native to southeastern Europe and western Asia but has been introduced and cultivated in temperate regions worldwide. It is often grown in gardens and farms, and in some places it behaves as a persistent weed or invasive plant due to its ability to spread aggressively from root fragments left in the soil.
Culinary uses
The root is harvested and prepared as a condiment, especially in horseradish sauce and relishes. It is also sometimes used as a substitute for wasabi in Japanese cuisine.
History and uses
Horseradish has been cultivated for at least two millennia and has a long history of medicinal and culinary use. Historical sources note that both the root and leaves were used medicinally in the Middle Ages. In modern times, it is also used in laboratories as a source of horseradish peroxidase, an enzyme important in biochemistry.
