The seed contains up to 45% of an edible semi-drying oil, it is used as a luminant, lubricant, in soap making etc[13, 21, 57, 142].

  • Medicinal Use

    The root is emollient and diuretic[240]. The juice of the roots is used in the treatment of chronic coughs and bronchial catarrh[240, 269].

    The seed, powdered, with salt is said to be a folk remedy for cancer[269].

    Rape oil is used in massage and oil baths, it is believed to strengthen the skin and keep it cool and healthy. With camphor it is applied as a remedy for rheumatism and stiff joints[269].

  • Edible Use

    Leaves – cooked as a potherb[183]. A mild, cabbage-like flavour[K].

    Root – raw or cooked[1, 16, 46, 171, 183]. A richer flavour than turnips, it makes a good cooked vegetable and, when finely grated, is acceptable in mixed salads[183, K]. The root can be 30cm or more in diameter, though it is usually eaten smaller since it then is more tender[K]. It is available from early autumn, and can either be left in the ground over winter to be harvested as required, or can be harvested and stored in a cool, frost-free place where it will keep for 6 months[K].

Cultivation & Habitat

Seed – sow April to June in situ.
Succeeds in full sun in a well-drained fertile preferably alkaline soil[16, 200]. Prefers a stiff moist soil and a fairly high rainfall[16, 20, 26]. Another report says that it prefers a light but rich soil and an open sunny position[264]. Succeeds in any reasonable soil[52]. Sunny days and cool nights are favourable for plant growth whilst dry weather at harvest time is essential[269]. Swede is reported to tolerate an annual precipitation of 30 to 280cm, an annual average temperature range of 5 to 27¡C and a pH in the range of 4.2 to 8.2[269]. Very young plants are susceptible to cold damage, -4¡C either killing or injuring seedlings, whereas -2¡C has no affect when the plants are more than one month old[269]. The garden swede is often cultivated for its edible root, there are several named varieties[183]. The plant is somewhat hardier than turnips and in most parts f Britain it can usually be left outdoors all winter and harvested as required. Plants take 4 – 6 weeks longer to mature than turnips[183]. Swede is 70% self-pollinating and 30% cross-pollinated. Even if wind and insects are absent, seed are still produced. Yield increases with honeybees[269]. A good companion plant for peas but it dislikes growing with hedge mustard and knotweed[18].
A hybrid of garden origin between B. napus and B. campestris.
