Safety & Hazards

The oil contained in the seed of some varieties of this species can be rich in erucic acid which is used in industry but is toxic if consumed. However, modern cultivars have been selected for culinary use which are almost free of erucic acid[1].

Cultivation Details

HabitAnnual/Biennial
Growth—

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[2]. Succeeds in full sun in a well-drained fertile preferably alkaline soil[3]. Succeeds in any reasonable soil[4]. Prefers a heavy soil and cool moist conditions[5, 6]. Tolerates a pH in the range 4.2 to 8.3. Plants are intolerant of root disturbance and so should not be transplanted[3]. Rape kale is 70% self-pollinating and 30% cross-pollinated. Even if wind and insects are absent, seed are still produced. Yield increases with the presence of honeybees[2]. This species is closely related to Brassica rapa[3].
