Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Edible Uses

Edible Parts: Leaves  Oil  Oil
Edible Uses: Oil  Oil

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].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Antiscorbutic

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].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Other Uses

Oil  Oil

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].

Special Uses

Cultivation details

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].
