Horseradish is a common perennial of waste ground, railway cuttings and roadside verges mainly in England. Arriving here from western Asia sometime before the 16th century, the use of prepared Horseradish roots as a condiment for meat quickly became popular. But the preparation of Horseradish is pretty hard-going - the pungent roots can cause tears worse than those from chopping an onion! Today, commercial production is widespread.

How to identify

A bushy, lettuce-like plant, Horseradish has long, crinkled, oval leaves and tiny, white flowers that appear in clusters on the long stem.


Mostly found in England.

Did you know?
