The seed contains up to 45% of a semi-drying oil. It is used as a lubricant, luminant and in soap making[1, 46, 57, 61, 74, 171].

  • Medicinal Use

    The tuberous roots and seeds are considered to be antiscorbutic[243]. A rather strange report, the leaves are much more likely to contain reasonable quantities of vitamin C than the roots or seeds[K].

  • Edible Use

    Leaves – raw or cooked. A strong radish/cabbage flavour.

    An edible oil is obtained from the seed, it is best when cold pressed[171]. Some varieties are rich in erucic acid which can be harmful[K].

  • Cautionary Notes

    The oil contained in the seed of some varieties of this species can be rich in erucic acid which is toxic. However, modern cultivars have been selected which are almost free of erucic acid.

Cultivation & Habitat

Seed – sow spring or autumn in situ.
Succeeds in full sun in a well-drained fertile preferably alkaline soil[16, 200]. Succeeds in any reasonable soil but prefers one on the heavy side[16]. Tolerates a pH in the range 4.8 to 8.3. This is the wild form of the turnip with a non-tuberous tap-root[17]. It is closely related to the cultivated forms that are grown for their edible oil-bearing seeds[17].
Europe – Mediterranean. Naturalized in Britain[17].
