Physical Characteristics
Annual growing to 1.2m.
It is hardy to zone 0 and is not frost tender. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, flies.
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils.
The plant prefers acid, neutral and basic (alkaline) soils.
It can grow in semi-shade (light woodland) or no shade.
It requires moist soil.
Young leaves - raw or cooked[2, 105]. A somewhat hot taste, they are finely cut and added to salads or used as a potherb[183]. It is best to use just the young leaves in spring, older leaves soon become bitter[9].
Seed - raw or cooked. A very pungent flavour, the seed can be ground into a powder and made into a paste when it is an excellent substitute for mustard[2, 9, 115, 183].
The sprouted seeds have a somewhat hot spicy flavour and are a tasty addition to salads[183].
Flowers - raw. A nice addition to salads. The flower buds are used as a broccoli substitute, they should be lightly steamed for no more than 5 minutes[9].
Young seedpods - raw. Crisp and juicy, they must be eaten when young because they quickly become tough and fibrous[K].
An edible oil is obtained from the seed[115].
