BOTANICAL NAME: Armoracia rusticana syn. A. lapathifolia
COMMON NAME: Horseradish
ORIGIN: Eastern Europe
FAMILY: Brassicaceae syn. Cruciferae
PLANT DESCRIPTION
A perennial to 1.5m high on a tapering, fleshy taproot to 60 cm long and 5 cm thick, it has large basal leaves, 30-100 cm long, with toothed margins. The white flowers appear mid-summer to mid-autumn. It tolerates damp soils and grows vigorously. It does best in temperate climates, to the point of becoming an 'edible weed' in some gardens. In warmer, more humid areas it can still be productive but is prone to attack by caterpillars in autumn. In tropical zones it is unlikely to do well, Horseradish tree is a good alternative. It should be planted in a permanent position and not be disturbed as new plants will arise from any broken roots and it would quickly become invasive if cultivated.
USES
Food: the fresh roots are used for flavouring meats, vegetables and pickles. They are also processed into sauce and vinegar. Young leaves have a pleasant flavour and can be added to salads or cooked as a potherb. Sprouted seeds are eaten in salads. Roots can be brought indoors in winter and forced into producing white, tender, sweet leaves. In Germany, sliced roots are cooked like parsnips.
Nutrient cycler: this deep rooted plant can be used in orchards to open up compacted soils and return nutrients to the surface of the soil.
PLANTING DETAILS
Recommended planting time: propagate by root or crown division in spring or autumn. Take root cuttings 60mm long or shorter, if plant material is limited. Lay the cuttings horizontally in a prepared garden site or a styrofoam box filled with potting mix. The cuttings should be buried 3 cm deep. Keep moist until the first leaves appear.
Sowing rate: space 50cm apart
