Horse Radish

Armoracia rusticana | Also known as: Red Cole, Pepper Root, Pepper turnip, Horseradish, Cochlearia armoracia | Rating: 1 votes | Print / Pdf

Perfect with your Sunday roast beef, or your Sunday roast horse.

A fast growing, tough perennial that has delightfully aromatic tap-roots. The leaves are large and bright green, and in early summer it blooms with tiny white flowers. As you’ve probably guessed by the name, Horse Radish, the pungent roots are edible, and are used for making horse radish. You probably wouldn’t plant Armoracia rusticana for the blooms, as it has a short flowering season, but it certainly is worth it for the smell that it’ll add to your garden. Simple to grow, Horse Radish enjoys full sunlight or partial shade.
